GRANVILLE T. WOODS
During his lifetime, Granville Woods
obtained some 50 patents. Granville T. Woods is sometimes called the "Black
Thomas Edison" because he invented so many electrical devices. During his
lifetime Granville woods obtained more than fifty patents for electrical devices that he
invented. Granville was called an "extremely prolific and brilliant
inventor." He was born in Columbus, Ohio, where he attended school until the
age of ten. When he was sixteen years old, Granville got a job as a fireman-engineer
with the railroad. He also began to study electrical and mechanical
engineering. In 1887, Granville made the most important invention of his time.
He invented a railway
This invention allowed crew members on
moving trains to communicate with one another and with railroad stations. It made
rail traffic safer because it helped trains to avoid collisions. Serious accidents
could also be avoided because conductors could be forewarned of obstacles in the train's
path. Another of Granville's inventions was a regulator which made electrical motors
run better. Demands for his equipment became so widespread that he quit his regular
job to devote full-time work for further inventions. An overhead conducting system for
electric railways, is still used by trains and trolley cars today. In 1884, he
invented a steam
boiler furnace. He next invented an amusement apparatus.
In 1890, he invented an electrically heated
egg incubator which made it possible to hatch 50,000 eggs at a time. Granville also
invented a relay instrument, and automatic air brake, an electric battery, a telephone
transmitter, and devices for telegraph and railway systems. Granville sold many of
his inventions to such large electrical companies as General Electric, Westinghouse, and
Bell Telephone. At the time of his death in 1910, Granville T. Woods' achievements
had gained him worldwide attention and recognition.
