THOMAS EDISDON Name:Thomas Alva EdisonBirth Date:February 11, 1847Death Date:October 18, 1931Place of Birth:Milan, Ohio, United StatesPlace of Death:West Orange, New Jersey, United StatesNationality:AmericanGender:MaleOccupations:inventor Thomas Alva Edison was born to Sam and Nancy on February 11, 1847, in Milan, Ohio. Known as "Al" in his youth, Edison was the youngest of seven children, four of whom survived to adulthood. Edison tended to be in poor health when young. To seek a better fortune, Sam Edison moved the family to Port Huron, Michigan, in 1854, where he worked in the lumber business. Addled Brain? Edison was a poor student. When a schoolmaster called Edison "addled," or slow. his furious mother took him out of the school and proceeded to teach him at home. Edison said many years later, "My mother was the making of me. She was so true, so sure of me, and I felt I had some one to live for, some one I must not disappoint." At an early age, he showed a fascination for mechanical things and for chemical experiments. In 1859, Edison took a job selling newspapers and candy on the Grand Trunk Railroad to Detroit. In the baggage car, he set up a laboratory for his chemistry experiments and a printing press, where he started the "Grand Trunk Herald", the first newspaper published on a train. An accidental fire forced him to stop his experiments on board. Loss of Hearing Around the age of twelve, Edison lost almost all his hearing. There are several theories as to what caused his hearing loss. Some attribute it to the aftereffects of scarlet fever which he had as a child. Others blame it on a conductor boxing his ears after Edison caused a fire in the baggage car, an incident which Edison claimed never happened. Edison himself blamed it on an incident in which he was grabbed by his ears and lifted to a train. He did not let his disability discourage him, however, and often treated it as an asset, since it made it easier for him to concentrate on his experiments and research. Undoubtedly, though, his deafness made him more solitary and shy in dealings with others. Work as a Telegraph Operator In 1862, Edison rescued a three-year-old from a track where a boxcar was about to roll into him. The grateful father, J.U. MacKenzie, taught Edison railroad telegraphy as a reward. That winter, he took a job as a telegraph operator in Port Huron. In the meantime, he continued his scientific experiments on the side. Between 1863 and 1867, Edison migrated from city to city in the United States taking available telegraph jobs. Love of Invention In 1868, Edison moved to Boston where he worked in the Western Union office and worked even more on his inventions. In January 1869 Edison resigned his job, intending to devote himself fulltime to inventing things. His first invention to receive a patent was the electric vote recorder, in June 1869. Daunted by politicians' reluctance to use the machine, he decided that in the future he would not waste time inventing things that no one wanted. Edison moved to New York City in the middle of 1869. A friend, Franklin L. Pope, allowed Edison to sleep in a room at Samuel Laws' Gold Indicator Company where he was employed. When Edison managed to fix a broken machine there, he was hired to manage and improve the printer machines. http://inventors.about.com/library/i...s/bledison.htm |

John Logie Baird - the inventor of mechanical television.. John Logie Baird was born on August 13th, 1888, in Helensburgh, Dunbarton, Scotland and died on June 14th, 1946, in Bexhill-on-Sea, Sussex, England. John Logie Baird received a diploma course in electrical engineering at the Glasgow and West of Scotland Technical College (now called Strathclyde University), and studied towards his Bachelor of Science Degree in electrical engineering from the University of Glasgow, interrupted by the outbreak of W.W.I. John Logie Baird is remembered as being an inventor of a mechanical television system. In the 1920's, John Logie Baird and American Clarence W. Hansell patented the idea of using arrays of transparent rods to transmit images for television and facsimiles respectively. Baird's 30 line images were the first demonstrations of television by reflected light rather than back-lit silhouettes. John Logie Baird based his technology on Paul Nipkow's scanning disc idea and later developments in electronics. The television pioneer created the first televised pictures of objects in motion (1924), the first televised human face (1925) and a year later he televised the first moving object image at the Royal Institution in London. His 1928 trans-atlantic transmission of the image of a human face was a broadcasting milestone. Color television (1928), stereoscopic television and television by infra-red light were all demonstrated by Baird before 1930. He successfully lobbied for broadcast time with the British Broadcasting Company, the BBC started broadcasting television on the Baird 30-line system in 1929. The first simultaneous sound and vision telecast was broadcast in 1930. In July 1930, the first British Television Play was transmitted, "The Man with the Flower in his Mouth." In 1936, the British Broadcasting Corporation adopted television service using the electronic television technology of Marconi-EMI (the world's first regular high resolution service - 405 lines per picture), it was that technology that won out over Baird's system. http://inventors.about.com/library/i...rs/blbaird.htm |

ALEXANDER FLEMING THE INVENTOR OF PENICILLIN Penicillin was discovered by chance, in 1928, after Alexander Fleming accidentally left a dish of staphylococcus bacteria uncovered for a few days. He returned to find the dish dotted with bacterial growth, apart from one area where a patch of mold (Penicillin notatum) was growing. The mold produced a substance, named penicillin by Fleming, which inhibited bacterial growth and was later found to be effective against a wide range of harmful bacteria.THE STORY RELATED INFO WEB SITES QUOTATIONSInventor:Alexander Fleming (Sir) Career:author, biologist and pharmacologist.Birth:August 6,1881 in East Ayrshire, ScotlandDeath:March 11, 1955 in London, EnglandNationality:ScottishInvention:Penicillin Function:noun / pen·i·cil·lin / named by Alexander FlemingDefinition:Any of a group of broad-spectrum antibiotic drugs obtained from penicillium molds or produced synthetically, most active against gram-positive bacteria and used in the treatment of various infections and diseases.
