An argument can be made that Benjamin Franklin may be the most famous American inventor, but without a doubt the most prolific and influential American inventor was Thomas Alva Edison. It is indeed difficult to imagine the modern world without scientific contributions and inventions of Edison. Nevertheless, Edison did have failures, including his failed support of DC power over AC power, but Edison never let failure stand between him and success. Known as the Wizard of Menlo Park, Edison received over one thousand US patents, the first of which was filed on October 13, 1868, when he was the tender age of 21. Perhaps Edison’s most famous inventions were the phonograph, motion pictures and the light-bulb. Truth be told, however, he really didn’t “invent” the lightbulb, but rather he improved upon the technology by developing a light-bulb that used a lower current electricity, a small carbonized filament, and an improved vacuum inside the globe. Edison’s invention lead to a reliable, long-lasting source of light.

» Selected Inventions of Edison

1868	Edison executed a patent application for his electric vote recorder, for which he later is issued his first patent.
1874	Edison invents the quadruplex telegraph, ownership of which is disputed by Western Union and Jay Gould’s Atlantic and Pacific Telegraph Company.
1875	Edison invents an “autographic press” kit, to be used to assist businesses in making copies of documents. The kit included an electric pen, a small battery, a press, ink, and supplies.
1877	Edison worked on a telephone transmitter that greatly improved on Alexander Graham Bell’s work with the telephone. His transmitter made it possible for voices to be transmitted at higer volume and with greater clarity over standard telephone lines.
1879	Using lower current electricity, a small carbonized filament, and an improved vacuum inside the globe, Edison was able to produce a reliable, long-lasting source of light.
1880	The commercial production of electric lamps begins at the Edison Lamp Works in Menlo Park.
1881	Edison executes twenty-three patent applications on electric lighting.
1882	During the spring and summer Edison executed fifty-three patent applications covering electric lighting, electric railways, and secondary batteries. An additional thirty-four patent applications covering electric lighting and electric railways were executed by Edison during the fall.
1885	Edison executed seventeen patent applications covering various embodiments of hi telegraph and telephone inventions. He also executes the first of four major patent caveats for the kinetoscope and kinetograph.
1888	Edison executes twenty-two patent applications for phonographs and cylinder records.
1891	Executes patent applications for the kinetoscope and kinetograph.
1896	Edison introduces the Edison Home Phonograph, an inexpensive, spring motor driven phonograph.
1900	Edison executes a patent application on a method of mass producing cylinder phonograph records.
1902	Successfully conducts the first road tests of electric vehicles equipped with Edison storage batteries and initiates production of alkaline storage battery.
1906	Edison receives a gold medal from the Royal Academy of Sciences in Sweden for his inventions in connection with the phonograph and the incandescent light.
