Transcript of Top Five Inventors
-January of 1826 in New York, Samuel Morse becomes a founder and first president of the National Academy of Design Whitney is most famous for his cotton gin, created in 1793 and pattented in 1794. -1827 Morse helps launch the New York Journal of Commerce and publishes Academics of Art. During his voyage home to New York in 1832 on the Sully, Samuel Morse first conceives the idea of the electromagnetic telegraph during his conversations with another passenger, Dr. Charles T. Jackson of Boston. So Ben began writing letters at night and signing them with the name of a fictional widow, Silence Dogood. Dogood was filled with advice and very critical of the world around her, particularly concerning the issue of how women were treated. Ben would sneak the letters under the print shop door at night so no one knew who was writing the pieces. After 16 letters he revealed his identity Benjamin Franklin As a result, the South became even more dependent on plantations and slavery. The number of slaves increased from around 700,000 in 1790 to around 3.2 million in 1850. Benjamin Franklin was born in Boston on January 17, 1706. He was the tenth son of 17 children. By November, 1837,
a message can be sent through ten miles of wire arranged on reels in Dr. Gale's university lecture room. In September, Alfred Vail, an acquaintance of Morse, witnesses a demonstration of the telegraph. The cotton gin changed the world dramatically, especially the southern United States. By 1860, the southern states were providing two-thirds of the world's supply of cotton. In 1840 Samuel Morse is granted a United States patent for his telegraph When Whitney was 14 years old, he made a violin from scratch. He spend most of his childhood years tinkering with tools in his dad's work shop, trying to create new things. When he was 19 he attended Yale university. When Benjamin was 15 his brother started The New England Courant the first "newspaper" in Boston. Eli Whitney died on January 8, 1825. It isn't known for sure exactly how he died, but most say it was from prostate cancer. He was buried in Grove Street Cemetery in New Haven, Connecticut. Alexander Graham Bell was born on March 3, 1847 in Edinburgh, Scotland. In 1729, Benjamin Franklin bought a newspaper, the Pennsylvania Gazette. Franklin not only printed the paper, but often contributed pieces to the paper under aliases. His newspaper soon became the most successful in the colonies. This newspaper, among other firsts, would print the first political cartoon, authored by Ben himself. Edward Jenner As a child, Alexander displayed a natural curiosity for the world, experimenting at a very young age. At 15 he entered Royal High School after years of homeschooling. He received poor grades and eventually moved to London with his grandfather where his first experiments with sound were started. In 1863, Alexander's father took him and his brother to see a unique machine, developed by Sir Charles Wheatstone. The "mechanical man" simulated a human voice and Alexander and his brother Melville were fascinated by it. They decided to build their own version of the robot human head. This is when Bell's experiments with voice and sound took off. In 1733 he started publishing Poor Richard's Almanack. Almanacs of the era were printed annually, and contained things like weather reports, recipes, predictions and homilies. Franklin published his almanac under the guise of a man named Richard Saunders, a poor man who needed money to take care of his carping wife. Among Franklin's other inventions are swim fins, the glass armonica (a musical instrument) and bifocals. By 1874, Bell had his telegraph almost complete. However he couldn't figure out how to allow multiple messages to be sent at one time without the wires crossing. On March 10, 1876, three days after his patent was issued, Bell succeeded in getting his telephone to work, using a liquid transmitter. Vibration of the diaphragm caused a needle to vibrate in the water, varying the electrical resistance in the circuit. When Bell spoke the famous sentence "Mr Watson, Come here, I want to see you" into the liquid transmitter, Watson, listening at the receiving end in a neighboring room, heard the words clearly. The Examiner approved Bell's patent on March 3, 1876. Edward Jenner was born on 17 May 1749 (6 May Old Style) in Berkeley, as the eighth of nine children. Alexander Graham Bell died on August 2, 1922 in Nova Scotia, Canada. He died from complications with diabetes at the age of 75. Kelley Darah Catie Roman Working in an agricultural community, Jenner knew of the country folklore that milkmaids never caught smallpox. They were known for their relatively flawless complexions, which were unmarked by smallpox scarring. However, they inevitably caught cowpox through their close work with cows. Jenner speculated that a bout of cowpox produced immunity against smallpox Catie Roman and Danielle Sarhan Kelley Darah and Kristen Weiss Catie Roman and Kelley Darah Edward died on 26 January 1823 in Berkeley, Gloucestershire at the age of 73. He was buried in the family tomb beside the altar in Berkeley Church, next to his parents, son, and wife Catherine. Edward Jenner became world famous following his publication in 1798 where he demonstrated that vaccination with cowpox prevented the deadly smallpox. As use of his treatment spread, he found that he had to spend more and more of his time answering questions about it. He called himself 'The Vaccine Clerk to the World'. He continued to advise and research on the safest ways to produce and transport his cowpox vaccine. Jenner's vaccine also laid the foundation for contemporary discoveries in immunology, and the field he began may someday lead to cures for arthritis, AIDS, and many other diseases. Made by:
