Thomas Edison's Inventions
Bambi Battle
After Thomas Edison moved to the Menlo Park Laboratory he promised he
would turn out a minor
invention every 10 days and a "big trick" every six months. Edison and
his staff were working on as many as
40 projects at one time and he was applying for nearly 400 patents each
year during this time. Thomas
Edison employed many people at his laboratories and under his direction
they handled the bulk of the
design, research and experimentation on the projects.
All told, Thomas Edison received patents for 1093 inventions, as either
sole inventor or co-inventor. He
received 389 for electric light and power, 195 for the phonograph, 150
for the telegraph, 141 for storage
batteries, and 34 for the telephone.
These are just a few of the 1093 patents issued to inventions
of
Thomas Alva Edison.
