Charles Darwin FRS

DarwinEnglish naturalist Charles Robert Darwin, FRS was born in The Mount, Shrewsbury, Shropshire, England on 12 February 1809. He was the grandson of Erasmus Darwin on his father’s side, and of Josiah Wedgwood on his mother’s side. As an eight-year-old Charles already had a taste for natural history and collecting. From September 1818 he joined his older brother Erasmus at the Anglican Shrewsbury School as a boarder. Darwin spent the summer of 1825 as an apprentice doctor, helping his father treat the poor of Shropshire, before going to the University of Edinburgh Medical School with his brother Erasmus in October 1825. In Darwin’s second year he joined the Plinian Society, a student natural history group whose debates strayed into radical materialism. He assisted Robert Edmond Grant’s investigations of the anatomy and life cycle of marine invertebrates in the Firth of Forth, and on 27 March 1827 presented at the Plinian his own discovery that black spores found in oyster shells were the eggs of a skate leech.

DarwinHe learned classification of plants, and assisted with work on the collections of the University Museum. Charles then went to to Christ’s College, Cambridge, for a Bachelor of Arts degree as the first step towards becoming an Anglican parson. His cousin William Darwin Fox introduced him to beetle collecting and He became a close friend and follower of botany professor John Stevens Henslow and met other leading naturalist. Darwin Stayed at Cambridge until June. He studied Paley’s Natural Theology, which made an argument for divine design in nature, explaining adaptation as God acting through laws of nature. He read John Herschel’s new book, which described the highest aim of natural philosophy and Alexander von Humboldt’s Personal Narrative of scientific travels. Inspired with “a burning zeal” to contribute, Darwin planned to visit Tenerife with some classmates after graduation to study natural history in the tropics. In preparation, he joined Adam Sedgwick’s geology course, then travelled with him, in order to map strata in Wales.

After a week with student friends at Barmouth, Darwin returned home on 29 August he learnt that Henslow had recommended him as suitable gentleman naturalist for a self-funded supernumerary place on HMS Beagle with captain Robert FitzRoy to chart the coastline of South America. The voyage began on 27 December 1831; it lasted almost five years.  Darwin spent most of that time on land investigating geology and making natural history collections, while the Beagle surveyed and charted coasts. He kept careful notes of his observations and theoretical speculations, and at intervals during the voyage his specimens were sent to Cambridge together with letters including a copy of his journal for his family. He had some expertise in geology, beetle collecting and dissecting marine invertebrates.On their first stop ashore at St. Jago, Darwin found that a white band high in the volcanic rock cliffs included seashells. Fitzroy gave him a volume of Charles Lyell’s Principles of Geology which set out uniformitarian concepts of land slowly rising or falling over immense periods, and Darwin saw things Lyell’s way, theorising and thinking of writing a book on geology. In Brazil Darwin was delighted by the tropical forest, but detested the sight of slavery. At Punta Alta in Patagonia he made a major find of fossil bones of huge extinct mammals in cliffs beside modern seashells, indicating recent extinction with no signs of change in climate or catastrophe.

He identified the little known Megatherium by a tooth and its association with bony armour which resembled a giant armadillo. The finds brought great interest when they reached England. On rides into the interior to explore geology and collect more fossils he gained social, political and anthropological insights into both native and colonial people at a time of revolution, and learnt that two types of rhea had separate but overlapping territories. Further south he saw stepped plains of shingle and seashells as raised beaches showing a series of elevations. He read Lyell’s second volume but his discoveries and theories challenged Lyell’s ideas of smooth continuity and of extinction of species. Darwin also experienced an earthquake in Chile and saw signs that the land had just been raised, including mussel-beds stranded above high tide. High in the Andes he saw seashells, and several fossil trees that had grown on a sand beach. He theorised that as the land rose, oceanic islands sank, and coral reefs round them grew to form atolls. On the geologically new Galápagos Islands Darwin looked for evidence attaching wildlife to an older “centre of creation”, and found mockingbirds allied to those in Chile but differing from island to island. He heard that slight variations in the shape of tortoise shells showed which island they came from. The Beagle investigated how the atolls of the Cocos (Keeling) Islands had formed, and the survey supported Darwin’s theories.

When the Beagle reached Falmouth, Cornwall, on 2 October 1836, Darwin was already a celebrity in scientific circles in December 1835 after selected naturalists had been given a pamphlet of his geological letters. hurried to Cambridge to see Henslow, who advised on finding naturalists available to catalogue the collections and agreed to take on the botanical specimens. Darwin’s father organised investments, enabling his son to be a self-funded gentleman scientist, and an excited Darwin went round the London institutions being fêted and seeking Zoologists and otherexperts to describe the huge collections.Darwin was introduced to the anatomist Richard Owen, who had the facilities of the Royal College of Surgeons to work on the fossil bones collected by Darwin. Owen’s surprising results included other gigantic extinct ground sloths as well as the Megatherium, a near complete skeleton of the unknown Scelidotherium and a hippopotamus-sized rodent-like skull named Toxodon resembling a giant capybara. The armour fragments were actually from Glyptodon, a huge armadillo-like creature. Darwin realised that these extinct creatures were related to living species in South America.Darwin wrote his first paper, showing that the South American landmass was slowly rising, and read it to the Geological Society of London and presented his mammal and bird specimens to the Zoological Society. The ornithologist John Gould soon announced that the Galapagos birds that Darwin had thought a mixture of blackbirds, “gros-beaks” and finches, were, in fact, twelve separate species of finches.Darwin was also elected to the Council of the Geological Society

Darwin then moved to London and joined Lyell’s social circle of scientists and experts such as Charles Babbage and writer Harriet Martineau who promoted Malthusianism underlying the controversial Whig Poor Law reforms to stop welfare from causing overpopulation and more poverty. Transmutation was anathema to Anglicans defending social order,but reputable scientists openly discussed the subject and there was wide interest in John Herschel’s letter praising Lyell’s approach as a way to find a natural cause of the origin of new species. Darwin learnt that the Galápagos mockingbirds from different islands were separate species, not just varieties, and what Darwin had thought was a “wren” was also in the finch group. The two rheas were also distinct species. Darwin then started writing about Transmutation of Species, and speculated about the possibility that “one species does change into another” to explain the geographical distribution of living species such as the rheas, and extinct ones such as the strange Macrauchenia which resembled a giant guanaco. Darwin Speculated boutlifespan, reproduction, variations in offspring to alter and adapt to different environments using the Galápagos tortoises, mockingbirds and rheas as examples postulating a single evolutionary tree containing common ancestors. While developing this intensive study of transmutation, Darwin became mired in more work. Still rewriting his Journal, he took on editing and publishing the expert reports on his collections, and with Henslow’s help obtained a Treasury grant of £1,000 to sponsor this multi-volume Zoology of the Voyage of H.M.S. Beagle, he also planned books on geology.Sadly all this work took it’s toll on Darwin’s health so he took a break in the countryside in Staffordshire where he met his future wife Emma Wedgewood and also formed a new & important theory” regarding the earthworms role in soil formation which Darwin presented at the Geological Society and Darwin became Secretary of the Geological Society. Despite the grind of writing and editing the Beagle reports, Darwin made remarkable progress on transmutation.

Darwin’s health deteriorated and For the rest of his life, he was repeatedly incapacitated with episodes of stomach pains, vomiting, severe boils, palpitations, trembling and other symptoms, particularly during times of stress. During another break he went “geologising” in Scotland. He visited Glen Roy in glorious weather to see the parallel “roads” cut into the hillsides at three heights. After recuperating he returned to Shrewsbury and Continuing his research in London, Darwin’s wide reading now included the sixth edition of Malthus’s An Essay on the Principle of Population, and asserted that human “population, when unchecked, goes on doubling itself every twenty five years, or increases in a geometrical ratio”, a geometric progression so that population soon exceeds food supply in what is known as a Malthusian catastrophe & compare this to de Candolle’s “warring of the species” of plants and the struggle for existence among wildlife, explaining how numbers of a species kept roughly stable. favourable variations would make organisms better at surviving and passing the variations on to their offspring, & favourable variations would tend to be preserved, and unfavourable ones to be destroyed. The result of this would be the formation of new species.would result in the formation of new species.Darwin saw a similarity between farmers picking the best stock in selective breeding, and a Malthusian Nature so that “every part of newly acquired structure is fully practical and perfected”. He later called his theory natural selection. On 29 January Darwin and Emma Wedgwood were married at Maer in Shropshire.Darwin’s book The Structure and Distribution of Coral Reefs on his theory of atoll formation was also published in May 1842 and he then wrote his first draft of his theory of natural selection. Darwin completed his third geological book in 1846. He now renewed a fascination and expertise in marine invertebrates, dating back to his student days classifying the barnacles he had collected on the voyage, enjoying observing beautiful structures and thinking about comparisons with allied structures.

In an attempt to improve his chronic ill health, Darwin visited Malvern spa and benefited from hydrotherapy. After eight years of work on barnacles (Cirripedia), Darwin’s theory helped him to find “homologies” showing that slightly changed body parts served different functions to meet new conditions This earned him the Royal Society’s Royal Medal, and it made his reputation as a biologist & realised that divergence in the character of descendants could be explained by them becoming adapted to diversified places in the economy of nature.By the start of 1856, Darwin was investigating whether eggs and seeds could survive travelacross seawater to spread species across oceans.By the start of 1856, Darwin was investigating whether eggs and seeds could survive travel across seawater to spread species across oceans. Darwin began work on a “big book on species” entitled Natural Selection and also presented a thesis On the Tendency of Species to form Varieties; and on the Perpetuation of Varieties and Species by Natural Means of Selection to the Linnean Society. At first There was little immediate attention to this announcement of the theory & Despite suffering from ill health he was getting constant encouragement from his scientific friends.

Upon it’s publication On the Origin of Species proved unexpectedly popular, In the book, Darwin set out “one long argument” of detailed observations, inferences and consideration of anticipated objections, and states that many more individuals of each species are born than can possibly survive so there is a recurring struggle for existence, it follows that any being, if it changes in any manner helpful to itself, will have a better chance of surviving, and thus be naturally selected. From the strong principle of inheritance, any selected variety will tend to propagate its new and modified form. He put a strong case for common descent, but avoided the then controversial term “evolution”, The book aroused international interest, although there was less controversy than had greeted the popular Vestiges of the Natural History of Creation,The Church of England’s response was mixed. Darwin’s old Cambridge tutors Sedgwick and Henslow dismissed the ideas, but liberal clergymen interpreted natural selection as an instrument of God’s design.

Though Darwin’s illness kept him away from the public debates, he eagerly scrutinised the scientific response, commenting on press cuttings, reviews, articles, satires and caricatures, and corresponded on it with colleagues worldwide. Darwin had only said “Light will be thrown on the origin of man”. Despite repeated bouts of illness during the last years of his life, Darwin’s work continued. Having published On the Origin of Species as an abstract of his theory, he pressed on with experiments, research, and writing of his “big book”. He covered human descent from earlier animals including evolution of society and of mental abilities, as well as explaining decorative beauty in wildlife and diversifying into innovative plant studies.Enquiries about insect pollination led in 1861 to novel studies of wild orchids, showing adaptation of their flowers to attract specific moths to each species and ensure cross fertilisation. In 1862 Fertilisation of Orchids gave his first detailed demonstration of the power of natural selection to explain complex ecological relationships, making testable predictions. As his health declined, he lay on his sickbed in a room filled with inventive experiments to trace the movements of climbing plants. In 1882 he was diagnosed with what was called “angina pectoris” which then meant coronary thrombosis and disease of the heart. At the time of his death, the physicians diagnosed anginal attacks”, and “heart-failure”.He died at Down House on 19 April 1882. His last words were to his family, telling Emma “I am not the least afraid of death – Remember what a good wife you have been to me – Tell all my children to remember how good they have been to me”, then while she rested, he repeatedly told Henrietta and Francis “It’s almost worth while to be sick to be nursed by you”.

He was buried at Westminster Abbey close to Johnn Herschel and Sir Isaac Newton, at the request of His colleagues, and after public and parliamentary petitioning, by William Spottiswoode (President of the Royal Society) .Darwin had convinced most scientists that evolution as descent with modification was correct, and he was regarded as a great scientist who had revolutionised ideas. Though few agreed with his views on “natural selection” he was honoured in June 1909 by more than 400 officials and scientists from across the world who met in Cambridge to commemorate his centenary and the fiftieth anniversary of On the Origin of Species. During this period, which has been called “the eclipse of Darwinism”, scientists proposed various alternative evolutionary mechanisms which proved untenable. The development of the modern evolutionary synthesis from the 1930s to the 1950s, incorporating natural selection with population genetics and Mendelian genetics, suggested natural selection was the basic mechanism of evolution.

Abraham Lincoln

Abraham Lincoln, the 16th President of the United States, was born February 12, 1809 and was the serving President of the United States from March 1861 until his assassination in April 1865. Lincoln successfully led the United States through its greatest constitutional, military, and moral crisis – The American Civil War – preserving the Union. Reared in a poor family on the western frontier, Lincoln was mostly self-educated, and became a country lawyer, a Whig Party leader, Illinois state legislator during the 1830s, and a one-term member of the United States House of Representatives during the 1840s.

After a series of debates in 1858 that gave national visibility to his opposition to the expansion of slavery, Lincoln lost a Senate race to his arch-rival,Stephen A. Douglas. Lincoln, a moderate from a swing state, secured the Republican Party presidential nomination in 1860. With almost no support in the South, Lincoln swept the North and was elected president in 1860. His election was the signal for seven southern slave states to declare theirsecession from the Union and form the Confederacy. The departure of the Southerners gave Lincoln’s party firm control of Congress, but no formula for compromise or reconciliation was found. Lincoln explained in his second inaugural address: “Both parties deprecated war, but one of them would make war rather than let the Nation survive, and the other would accept war rather than let it perish, and the war came.”

When the North enthusiastically rallied behind the national flag after the Confederate attack on Fort Sumter on April 12, 1861, Lincoln concentrated on the military and political dimensions of the war effort. His goal was now to reunite the nation. As the South was in a state of insurrection, Lincoln exercised his authority to suspend habeas corpus, arresting and temporarily detaining thousands of suspected secessionists without trial. Lincoln averted British recognition of the Confederacy by skillfully handling the Trent affair in late 1861. His efforts toward the abolition of slavery include issuing his Emancipation Proclamation in 1863, encouraging the border states to outlaw slavery (mostly as a war policy), but did nothing to help push through Congress the Thirteenth Amendment to the United States Constitution, which finally freed all the slaves nationwide in December 1865. Lincoln closely supervised the war effort, especially the selection of top generals, including commanding general Ulysses S. Grant. Lincoln brought leaders of the major factions of his party into his cabinet and pressured them to cooperate. Under Lincoln’s leadership, the Union set up a naval blockade that shut down the South’s normal trade, took control of the border slave states at the start of the war, gained control of communications with gunboats on the southern river systems, and tried repeatedly to capture the Confederate capital at Richmond, Virginia. Each time a general failed, Lincoln substituted another until finally Grant succeeded in 1865.

An exceptionally astute politician deeply involved with power issues in each state, Lincoln reached out to War Democrats and managed his own re-election in the 1864 presidential election. As the leader of the moderate faction of the Republican party, Lincoln found his policies and personality were “blasted from all sides”: Radical Republicans demanded harsher treatment of the South, War Democrats desired more compromise, Copperheads despised him, and irreconcilable secessionists plotted his death. Politically, Lincoln fought back with patronage, by pitting his opponents against each other, and by appealing to the American people with his powers of oratory. His Gettysburg Address of 1863 became the most quoted speech in American history. At the close of the war, Lincoln held a moderate view of Reconstruction, seeking to reunite the nation speedily through a policy of generous reconciliation in the face of lingering and bitter divisiveness. Six days after the surrender of Confederate commanding general Robert E. Lee, however, Lincoln was assassinated by actor and Confederate sympathizer John Wilkes Booth. Lincoln’s death was the first assassination of a U.S. president and sent the nation into mourning. Lincoln has been consistently ranked by scholars and the public as one of the three greatest U.S. presidents, the others by scholars being George Washington and Franklin D. Roosevelt, and by the public, Ronald Reagan and Bill Clinton.

Steve Hackett (Genesis)

GenesisFormer Genesis member Steve Hackett was born 12th February 1950. English rock band Genesis were formed in 1967. The band currently consists of its three longest-tenured members – Tony Banks (keyboards) and Mike Rutherford (bass, guitar), who were founder members; and Phil Collins (vocals, drums), who first joined in 1970. Past members Peter Gabriel (vocals, flute), Steve Hackett (guitar) and Anthony Phillips (guitar) also played major roles in the band in its early years. Peter Gabriel left in 1975 to pursue a solo career and Following Gabriel’s departure, Collins became the group’s lead singer, and sang lead vocals, then Hackett left in 1977. Former Genesis singer and successful solo artist Peter Gabriel was also born 13th February 1950.

Genesis’s first album was Nursery Cryme was initially regarded by the band and the fans as a pop experiment, referring to then-popular melodic pop. Then, over the course of a year, (beginning with their second album in mid-1970) they quickly evolved into a progressive rock band with the incorporation of complex song structures and elaborate instrumentation. Their concerts became theatrical experiences with innovative stage design, pyrotechnics, extravagant costumes and on-stage stories.

This second phase was characterised by lengthy performances such as the 23-minute “Supper’s Ready” and the 1974 concept album, The Lamb Lies Down on Broadway. In the late ’70s and early ’80s the band’s musical direction changed once again, becoming more pop oriented and commercially accessible. This resulted in their first top 40 single in the US with “Follow You Follow Me”, their first number one album in the United Kingdom, Duke, and their only number one single in the United States, “Invisible Touch”. Genesis are among the top 30 highest-selling recording artists of all time, with approximately 150 million albums sold worldwide haves released many great albums, including INVISIBLE TOUCH, FOXTROT & GENESIS, Genesis were also inducted into the Rock and Roll Hall of Fame in 2010

Ray Manzarek(The Doors)

The_Doors_of_Perception_by_cheapexposureRay Manzarek, American keyboard player with The Doors was born 12th February 1939. The Doors were formed In the summer of 1965, when, after graduating from the UCLA. Morrison and fellow UCLA student Ray Manzarek formed the group during that same Summer of 1965. after meeingt months earlier as fellow cinematography students. Thereafter, drummer John Densmore and guitarist Robby Krieger auditioned and was then added to the lineup. All three musicians shared a common interest in the Maharishi Mahesh Yogi’s meditation practices at the time, attending scheduled classes, but Morrison was not involved in this series of classes, claiming later that he “did not meditate”. The Doors took their name from the title of Aldous Huxley’s book The Doors of Perception (a reference to the “unlocking” of “doors of perception” through psychedelic drug use). Huxley’s own title was a quotation from William Blake’s The Marriage of Heaven and Hell, in which Blake wrote: “If the doors of perception were cleansed everything would appear to man as it is, infinite.”

The Doors achieved national recognition after signing with Elektra Records in 1967. The single “Light My Fire” spent three weeks at number one on the Billboard Hot 100 chart in July/August 1967. Later, The Doors appeared on The Ed Sullivan Show, a popular Sunday night variety series that had introduced The Beatles and Elvis Presley to the United States. Ed Sullivan requested two songs from The Doors for the show, “People Are Strange”, and “Light My Fire”. Morrison also began writing during his adolescence. At UCLA he studied the related fields of theater, film, and cinematography.He self-published two separate volumes of his poetry in 1969, entitled The Lords / Notes on Vision and The New Creatures. The Lords consists primarily of brief descriptions of places, people, events and Morrison’s thoughts on cinema, but The New Creatures verses are more poetic in tone.

Thomas Edison

American inventor and businessman Thomas Alva Edison was born on February 11, 1847 in Milan, Ohio, and grew up in Port Huron, Michigan. In school, the young Edison’s mind often wandered, and his teacher, the Reverend Engle, was overheard calling him “addled”. This ended Edison’s three months of official schooling. Edison recalled later, “My mother was the making of me. She was so true, so sure of me; and I felt I had something to live for, someone I must not disappoint.” His mother taught him at home. much of his education came from reading R.G. Parker’s School of Natural Philosophy. Edison developed hearing problems at an early age. The cause of his deafness has been attributed to a bout of scarlet fever during childhood and recurring untreated middle-ear infections. Around the middle of his career,

Edison attributed the hearing impairment to being struck on the ears by a train conductor when his chemical laboratory in a boxcar caught fire and he was thrown off the train in Smiths Creek, Michigan, along with his apparatus and chemicals. In 1854 Edison’s family moved to Port Huron, Michigan, He sold candy and newspapers on trains running from Port Huron to Detroit, and he sold vegetables to supplement his income. He also studied qualitative analysis, and conducted chemical experiments on the train until an unfortunate accident. He obtained the right to sell newspapers on the road, and, with the aid of four assistants, he set in type and printed the Grand Trunk Herald, which he sold with his other papers. This began Edison’s long streak of entrepreneurial ventures, as he discovered his talents as a businessman. These talents eventually led him to found 14 companies, including General Electric, which is still one of the largest publicly traded companies in the world.

Thomas Edison began his career as an inventor in Newark, New Jersey, with the automatic repeater and his other improved telegraphic devices, but the invention that first gained him notice was the phonograph in 1877. This accomplishment was so unexpected by the public at large as to appear almost magical. Edison became known as “The Wizard of Menlo Park,” New Jersey.His first phonograph recorded on tinfoil around a grooved cylinder, but had poor sound quality and the recordings could be played only a few times. In the 1880s, a redesigned model using wax-coated cardboard cylinders was produced by Alexander Graham Bell, Chichester Bell, and Charles Tainter. This was one reason that Thomas Edison continued work on his own “Perfected Phonograph.” In 1877–78, Edison invented and developed the carbon microphone used in all telephones along with the Bell receiver until the 1980s. After protracted patent litigation, in 1892 a federal court ruled that Edison and not Emile Berliner was the inventor of the carbon microphone which was also used in radio broadcasting and public address work through the 1920s.

He also developed many other devices that greatly influenced life around the world, including the motion picture camera, and a long-lasting, practical electric light bulb Edison also patented a system for electricity distribution in 1880, which was essential to capitalize on the invention of the electric lamp. Dubbed “The Wizard of Menlo Park” by a newspaper reporter, he was one of the first inventors to apply the principles of mass production and large-scale teamwork to the process of invention, and because of that, he is often credited with the creation of the first industrial research laboratory.Edison is the fourth most prolific inventor in history, holding 1,093 US patents in his name, as well as many patents in the United Kingdom, France, and Germany. He is credited with numerous inventions that contributed to mass communication and, in particular, telecommunications.

These included a stock ticker, a mechanical vote recorder, a battery for an electric car, electrical power, recorded music and motion pictures.His advanced work in these fields was an outgrowth of his early career as a telegraph operator. Edison developed a system of electric-power generation and distribution to homes, businesses, and factories – a crucial development in the modern industrialized world. He also developed the first power station on Pearl Street in Manhattan, New York and is credited with designing and producing the first commercially available fluoroscope, a machine that uses X-rays to take radiographs. Until Edison discovered that calcium tungstate fluoroscopy screens produced brighter images than the barium platinocyanide screens originally used by Wilhelm Röntgen, the technology was capable of producing only very faint images, The fundamental design is still in use today.

Edison was active in business Just months before his death, the Electrical transmission for the Lackawanna Railroad inaugurated suburban electric train service from Hoboken to Montclair, Dover, and Gladstone in New Jersey. was by means of an overhead catenary system using direct current, which Edison had championed. Despite his frail condition, Edison was at the throttle of the first electric MU (Multiple-Unit) train to depart Lackawanna Terminal in Hoboken in September 1930, driving the train the first mile through Hoboken yard on its way to South Orange.This fleet of cars would serve commuters in northern New Jersey for the next 54 years until their retirement in 1984. A plaque commemorating Edison’s inaugural ride can be seen today in the waiting room of Lackawanna Terminal in Hoboken, which is presently operated by New Jersey Transit.

Edison was said to have been influenced by a popular fad diet in his last few years; “the only liquid he consumed was a pint of milk every three hours”. He is reported to have believed this diet would restore his health. Edison became the owner of his Milan, Ohio, birthplace in 1906. On his last visit, in 1923, he was reportedly shocked to find his old home still lit by lamps and candles.Thomas Edison died of complications of diabetes on October 18, 1931, in his home, “Glenmont” in Llewellyn Park in West Orange, New Jersey, which he had purchased in 1886 as a wedding gift for Mina. He is buried behind the home. Edison’s last breath is reportedly contained in a test tube at the Henry Ford Museum. Ford reportedly convinced Charles Edison to seal a test tube of air in the inventor’s room shortly after his death, as a memento.

NATIONAL INVENTORS DAY

National Inventors day takes place annually on February 11 to commemorate the birth of Thomas Edison and to recognise the contributions of inventors. It was started by Former US President Ronald Reagan, who proclaimed February 11, 1983 as National Inventors’ Day, In recognition of the enormous contribution inventors make to the nation and the world, the Congress designated February 11, the anniversary of the birth of the inventor Thomas Alva Edison, who held over 1,000 patents.

Some countries celebrate Inventors’ Day On different days; in Argentina Inventors’ Day Spanish: Día del Inventor) Is held annually on September 29, to commemorate the birthday of the inventor of the ballpoint pen, László József Bíró. Meanwhile The Inventors’ Day (German: Tag der Erfinder) in the German-speaking countries Germany, Austria and Switzerland takes place on November 9, and celebrates he birthday of the Austrian-born inventor and Hollywood actress Hedy Lamarr whose main invention was the frequency-hopped spread spectrum in 1942. The day was proclaimed by Berlin inventor and entrepreneur Gerhard Muthenthaler.

The aims of National Inventors day are to Encourage people towards their own ideas and for a change to the better and Remind people of forgotten inventors. Hungarian Inventors’ Day (Magyar Feltalálók Napja) is celebrated on June 13 in memoriam of Albert Szent-Györgyi who registered his national patent about the synthesized Vitamin C in 1941 and won the Nobel Prize in Physiology or Medicine in 1937. It is celebrated by the Association of Hungarian Inventors (MAFE) since 2009. While in the Republic of Moldova an Inventors’ and Rationalizers’ Day is celebrated annually at the end of June, Thailand celebrates Inventors’ Day on February 2 To commemorate the anniversary of His Majesty King Bhumibol Adulyadej’s allocation of a patent for a slow speed surface aerator on February 2, 1993.
