At age 15, Edison's began work as a telegraph operator, passing on telegraph messages. He chose the late-night shift -- which involved very little actual messaging -- because the free time allowed him to read and experiment. Company rules required that, once an hour, an operator send a code down the line to show he was present and alert. One of Edison's first inventions was a clock that would tap out the code on the hour, allowing him to read and experiment without being interrupted by his job! Thus, his first invention would have been at about the age of 16. Edison's first PATENT was in 1869, at age 22: a device that would allow all votes in a legislature to be recorded almost immediately, instead of spending several minutes of recording voice votes. Edison found out that nobody wanted a quick record of votes; legislators preferred to spend these minutes making last minute deals. He said that this epiphany made him resolve to only invent things that people actually wanted.

Thomas EDison had no illness, he just died of old age.
He didn't attend college. At the age of 12 he became a railroad newsboy and began to experiment with chemistry. Gaining the exclusive right to sell newspapers on his line and purchasing some old type he published the Grand Trunk Herald, the first newspaper printed in a train. A station master taught him telegraphy and he invented an automatic repeater so messages could be sent from wire to another without the use of an operator. He developed the system of duplex telegraphy while he was a telegraph operator in Boston. In 1871 he invented the printing telegraph and established a workshop at Newark, NJ. He moved to Menlo, NJ in 1876. He was now ready for a workshop to create hundred of inventions.
