1868 Came up with his first patented invention, an Electrical Vote
Recorder. Application for this patent was signed 0n October 11, 1968.
Because the invention was way ahead of its time, it was heartily
denigrated by
politicians... He now becomes much more oriented towards making certain
there is a strong public demand and associated market for anything he
tries to invent. (age 22)
1872-1876 Worked on and patented several
of his most important inventions, including the motograph and automatic
telegraph systems such as the quadruplex, sextuplex and multiplex
telegraph which saved Western Union many millions of dollars in wiring.
Also invented paraffin paper (which was first used for wrapping
candies), the electric pen, the forerunner of the present day mimeograph
machine, the carbon rheostat, the microtasimeter, etc.
etc, etc. these are some very informative sites. so for now i'll just put down some other sources, since i need five and only have 2.
