Until recently, Thomas Alva Edison was, for me, a famous American who had dabbled in science. However, my eyes were opened wide when I came to learn that Edison had 1,093 successful patents and around 600 unsuccessful patents. Moreover, in addition to having such a large number of patents, Edison's work was in areas that are at the very heart of much of what we take for granted now.
This page is just a small tribute to The Man of the Millennium, as I think he was voted at the end of 2000.
Thomas Alva Edison was born on 11 February 1847 in Milan, Ohio. With only three months of formal education he became one of the greatest inventors and industrial leaders in history. Edison obtained 1,093 United States patents, the most issued to any individual.
Edison's greatest contribution was the first practical electric lighting. He not only invented the first successful electric light bulb, but also set up the first electrical power distribution company. Edison invented the phonograph, and made improvements to the telegraph, telephone and motion picture technology. He also founded the first modern research laboratory.
Edison was also a good businessman. He not only designed important new devices, he created companies worldwide for the manufacture and sale of his inventions. Along with other manufacturing pioneers of his era, Edison helped make the United States a world industrial power. He and Henry Ford became friends after Edison encouraged Ford to use the gasoline powered engine for the automobile.
Edison was also a ruthless businessman who fought viciously to defeat his competitors. One of the most notorious examples of his competitive vigor were the lengths he went to to discredit Nicola Tesla's Alternating Current system, which is the system of electrical distribution in use today.
Edison had great faith in progress and industry, and valued long, hard work. He used to say, "Genius was 1 percent inspiration and 99 percent perspiration." Edison believed that inventing useful products offered everyone the opportunity for fame and fortune while benefiting society.

In summary, Edison's patents are grouped as follows:
light and power
and ore milling
sound and recording
Note: this total exceeds 1,093 due to double counting within some categories.
Edison's first patent, number 90646, was issued on 1 June 1869 and was for a Electrographic Vote Recorder and Register.
We read in the Patent Application, "The object of my invention is to produce an apparatus which records and registers in an instant, and with great accuracy the votes of legislative bodies, thus avoiding loss of valuable time …" this is what it looks like:
Edison's final patent, number 1908830 was granted on 16 May 1933 and was for a Holder for Article to be ElectroPlated and was an improvement on an earlier patent of his. His holder looks like this:
The electric light bulb is another one of Edison's major advances. Where would we be without them?
Edison worked on a large number of projects, as we can tell from the table above. The Sprocket Chain Drive is an example, away from telegraphy and phonography, of Edison's impact on the technology used in manufacturing. Patent number 954789 dated 12 April 1910 relates to a very simple idea … but no one had thought of it before.
Some of his ideas, whilst fully explained in his patent applications could make us wonder how on earth he thought of them, when he was so busy with everything else! What's this, do you think?
In fact, it's a "Device for viewing motion pictures"; and it was used by holding it in front of, and a short distance away from, one's eyes when watching "animated pictures in the present state of the art." Why did he invent this and what does it do to improve the lot of the cinema going public? Apparently, it "reduces considerably the objectionable flicker or scintillation, which is a well known defect of moving or animated pictures …"
