Inventors A - Z
in Columbus, Ohio, in April 23, 1856, Granville T. Woods dedicated his
life to developing a variety of inventions relating to the railroad industry.
To some he was known as the "Black Edison, both great inventors of their
time. Granville T. Woods invented more than a dozen devices to improve
electric railway cars and many more for controlling the flow of electricity.
His most noted invention was a system for letting the engineer of a train
know how close his train was to others. This device helped cut down accidents
and collisions between trains.
Granville T. Woods literally learned
his skills on the job. Attending school in Columbus until age 10, he served
an apprenticeship in a machine shop and learned the trades of machinist
and blacksmith. During his youth he also went to night school and took
private lessons. Although he had to leave formal school at age ten, Granville
T. Woods realized that learning and education were essential to developing
critical skills that would allow him to express his creativity with machinery.
In 1872, Granville T. Woods obtained
a job as a fireman on the Danville and Southern railroad in Missouri, eventually
becoming an engineer. He invested his spare time in studying electronics.
In 1874, Granville Woods moved to Springfield, Illinois, and worked in
a rolling mill. In 1878, he took a job aboard the Ironsides, a British
steamer, and, within two years, became Chief Engineer of the steamer. Finally,
his travels and experiences led him to settle in Cincinnati, Ohio, where
he became the person most responsible for modernizing the railroad.
In 1888, Granville T. Woods developed
a system for overhead electric conducting lines for railroads, which aided
in the development of the overhead railroad system found in cities such
as Chicago, St. Louis, and New York City. In his early thirties, he became
interested in thermal power and steam-driven engines. And, in 1889, he
filed his first patent for an improved steam-boiler furnace. In 1892, a
complete Electric Railway System was operated at Coney Island, NY. In 1887,
he patented the Synchronous Multiplex Railway Telegraph,
which allowed communications between train stations from moving trains.
Granville T. Woods' invention made it possible for trains to communicate
with the station and with other trains so they knew exactly where they
were at all times.
Graham Bell’s company purchased the rights to Granville T. Woods’ "telegraphony,"
enabling him to become a full-time inventor. Among his other top inventions
were a steam boiler furnace and an automatic air brake used to slow or
stop trains. Wood’s electric car was powered by overhead wires. It was
the third rail system to keep cars running on the right track.
Success led to law suits filed by
Edison who sued Granville Woods claiming that he was the first inventor
of the multiplex telegraph. Granville Woods eventually won, but Edison
didn’t give up easily when he wanted something. Trying to win Granville
Woods over, and his inventions, Edison offered Granville Woods a prominent
position in the engineering department of Edison Electric Light Company
in New York. Granville T. Woods, preferring his independence, declined.
