Thomas Edison, yes that light bulb maestro. He was a prolific inventor. By the time he died, he accumulated 1,093 US and 1300 foreign patents. He is well known for that. He is also known to have invented phonograph, build companies from startups (General Electric and RCA) and specialist in telegraphy.
Edison was the fastest transcribers of this day with Morse key. He did night duty mostly during that time. As a night-duty telegrapher, he was required to clock in every six hour to confirm he still manning the wire.
He did that for a while, until he invented an automatic solution that will clock in every six hour! So he can get away from his desk and spend the night on!
He was later fired from the job and started as a freelance telegrapher across US. He finally landed to New York where his creative genius about to take flight.
He realized he is unable to scale his invention with great idea alone. He was one of the first few inventor realized the false notion, “if you build it they will come.”
His first patent was an automatic vote recorder for the Massachusetts Legislature. While a brilliant idea in his time, it was never used and sold of at $100 to someone.
It is during his time in New York, Edison started to meet a lot more people and build his network. He started to partner with other engineers, mathematicians, lawyers, machinists and bankers. Edison started as a specialist, then he became a specializing-generalist.
