Form the History of Edison’s Inventions
In his 84 years, Thomas Edison acquired a record number of 1,093 patents (singly or jointly) and was the driving force behind such innovations as the phonograph, the incandescent light bulb and one of the earliest motion picture cameras. He also created the world’s first industrial research laboratory. Known as the “Wizard of Menlo Park,” for the New Jersey town where he did some of his best-known work, Edison had become one of the most famous men in the world by the time he was in his 30s. In addition to his talent for invention, Edison was also a successful manufacturer and businessman who was highly skilled at marketing his inventions–and himself–to the public.
Thomas Edison’s Early Life
Thomas Alva Edison was born on February 11, 1847, in Milan, Ohio. He was the seventh and last child born to Samuel Edison Jr. and Nancy Elliott Edison, and would be one of four to survive to adulthood. Thomas Edison received little formal education, and left school in 1859 to being working on the railroad between Detroit and Port Huron, Michigan, where his family then lived.
Did you know? By the time he died on October 18, 1931, Thomas Edison had amassed a record 1,093 patents: 389 for electric light and power, 195 for the phonograph, 150 for the telegraph, 141 for storage batteries and 34 for the telephone.
During the Civil War, Edison learned the emerging technology of telegraphy, and traveled around the country working as a telegrapher. He had developed serious hearing problems, which were variously attributed to scarlet fever, mastoiditis or a blow to the head. With the development of auditory signals for the telegraph, Edison was at a disadvantage, and he began to work on inventing devices that would help make things possible for him despite his deafness (including a printer that would convert the electrical signals to letters). In early 1869, he quit telegraphy to pursue invention full time.

Morse Code & the Telegraph
From 1870 to 1875, Edison worked out of Newark, New Jersey, where he developed telegraph-related products for both Western Union Telegraph Company (then the industry leader) and its rivals. Edison’s mother died in 1871, and that same year he married 16-year-old Mary Stillwell. Despite his prolific telegraph work, Edison encountered financial difficulties by late 1875, but with the help of his father was able to build a laboratory and machine shop in Menlo Park, New Jersey, 12 miles south of Newark.
In 1877, Edison developed the carbon transmitter, a device that improved the audibility of the telephone by making it possible to transmit voices at higher volume and with more clarity. That same year, his work with the telegraph and telephone led him to invent the phonograph, which recorded sound as indentations on a sheet of paraffin-coated paper; when the paper was moved beneath a stylus, the sounds were reproduced. The device made an immediate splash, though it took years before it could be produced and sold commercially, and the press dubbed Edison “the Wizard of Menlo Park.”
George Washington
(February 22, 1732[b] – December 14, 1799) was an American soldier, statesman, and Founding Father who served as the first President of the United States from 1789 to 1797. Appointed by the Continental Congress as commander of the Continental Army, Washington led the Patriot forces to victory in the American Revolutionary War, and presided at the Constitutional Convention of 1787, which established the Constitution of the United States and a federal government. Washington has been called the "Father of the Nation"[10] for his manifold leadership in the formative days of the country.
Washington's first public office was serving as official Surveyor of Culpeper County, Virginia from 1749 to 1750. Subsequently, he received his initial military training (as well as a command with the Virginia Regiment) during the French and Indian War. He was later elected to the Virginia House of Burgesses and was named a delegate to the Continental Congress. Here he was appointed Commanding General of the Continental Army. With this title, he commanded American forces (allied with France) in the defeat and surrender of the British at the Siege of Yorktown during the American Revolutionary War. He resigned his commission after the Treaty of Paris was signed in 1783.
Washington played an indispensable role in adopting and ratifying the Constitution of the United States. He was then twice elected president by the Electoral College unanimously. As president, he implemented a strong, well-financed national government while remaining impartial in a fierce rivalry between cabinet members Thomas Jefferson and Alexander Hamilton. During the French Revolution, he proclaimed a policy of neutrality while sanctioning the Jay Treaty. He set enduring precedents for the office of president, including the title "Mr. President", and his Farewell Address is widely regarded as a pre-eminent statement on republicanism.
Washington owned over a hundred slaves, and he signed measures passed by Congress to protect slavery, as well as measures passed by Congress to curtail slavery. Starting in 1778, he had become troubled with the institution of slavery and freed William Lee, one of his slaves, in his will. He freed the other 123 slaves that he owned upon the death of his wife, Martha Washington. She decided to respect her husband's wishes and freed these slaves on January 1, 1801, before her death. He also freed in his will 33 more slaves that he acquired in a prior debt agreement with his brother-in-law.[11][12] He endeavored to assimilate Native Americans into the Anglo-American culture but fought indigenous resistance during instances of violent conflict. He was a member of the Anglican Church and the Freemasons, and he urged broad religious freedom in his roles as general and president. Upon his death, he was eulogized as "first in war, first in peace, and first in the hearts of his countrymen".[13]
Washington has been memorialized by monuments, a federal holiday, various media, geographical locations, including the national capital, the State of Washington, stamps, and currency, and many scholars and polls rank him among the greatest U.S. presidents. In 1976, as part of commemorations for the U.S. Bicentennial, Washington was posthumously promoted to the rank of General of the Armies of the United States.
