Foulke, William Parker
William Parker Foulke was a US scientist and dinosaur artist who found the first American dinosaur skeleton, Hadrosaurus, a duck-billed dinosaur. The fossilized bones were found by workmen in a Cretaceous marl (a crumbly type of soil) pit on the John E. Hopkins farm in Haddonfield, New Jersey beginning in 1838. Foulke heard of the discovery and recognized its importance in 1858. The dinosaur was excavated and named by US anatomist Joseph Leidy who named it Hadrosaurus foulkii (meaning "Foulke's big lizard").
Farnsworth, Philo T.
Philo Taylor Farnsworth (1906-1971) was an American inventor. Farnsworth invented many important components of the television, including power, focusing systems, synchronizing the signal, contrast, controls, and scanning. He also invented a radar system, a cold cathode ray tube, a new type of baby incubator, and the first electronic microscope. Farnsworth held over 300 patents.
Model T carFord, Henry
Henry Ford (1863-1947) was an American engineer and industrialist who used the first conveyor belt-based assembly-lines in his car factory, revolutionizing factory production. Ford manufactured affordable cars and paid high wages to his factory workers, allowing workers to buy the cars they made. After early work as a machinist, Ford built a gasoline engine in 1893. In 1896, Ford built a "horseless carriage," which he called the "Quadricycle," which means "four wheels" (others, including Charles Edgar and J. Frank Duryea, Elwood Haynes, Hiram Percy Maxim, and Charles Brady King had built earlier "horseless carriage"). In 1899, Ford formed the Detroit Automobile Company (which was later called the Henry Ford Company and then the Cadillac Motor Car Company). Ford introduced the Model T in October 1908; it was a great success (every Model T was painted black). Ford introduced conveyor belt-based assembly-line factory production and a $5 daily wage in 1913-14 in Ford's Highland Park, Michigan plant (primitive assembly line production had been started in 1901 by Ransome Eli. Olds, another early car-maker). This type of production greatly reduced the amount of time taken to put each car together (93 minutes for a Model T) from its parts, reducing production costs.
Franklin, Benjamin
FranklinBenjamin Franklin (January 17, 1706-April 17, 1790) was an American statesman, writer, printer, and inventor. Franklin experimented extensively with electricity. In 1752, his experiments with a kite in a thunderstorm (never do this, many people have died trying it!) led to the development of the lightning rod. Franklin started the first circulating library in the colonies in 1731. He also invented bifocal glasses and the Franklin stove. The idea of daylight savings time was first proposed by Benjamin Franklin in 1784.
