Granville Tailer Woods was an American inventor who held more than fifty patents.[1]
Granville T. Woods was born free in Columbus, Ohio, on 23 April 1856. He was the son of Tennessee born Cyrus Tailer Woods and Virgina born Martha Brown.
In the 1860 census Granville (age 10) was in Martinsburg, Knox, Ohio, living with his parents and several inferred siblings.[2]In 1870 Granville was recorded living in Columbus, Ohio with his widowed mother, Martha, listed as a washer woman, and two inferred siblings. Granville's occupation was listed as Church Sexton. [3]
In 1872, he went west and obtained work as a fireman and later as an engineer on an Iron Mountain Railroad in Missouri. In his spare time he studied electricity. In December 1874 he moved to Springfield, Illinois, where he worked in a rolling mill, until early 1876, when he went east to begin two years of college study in mechanical and electrical engineering, while also working in a machine shop. Beginning in 1878 he spent two years at sea as an engineer on a British steamship. During 1880 he handled a locomotive on the D & S Railroad. [4]
In the 1880s he established a factory in Cincinnati, Ohio, for the manufacture of telephone, telegraph, and electrical instruments.[4]
One of his most significant inventions was a system intended for the engineer of a train to know how close he was to other trains. This prevented accidents and collisions between trains. He also invented the induction telegraph system, it allowed messages to be sent to and from trains, which also help prevent collision.
He and his brother organized Woods Electrical Company. The company prospered, as he was successful in selling his invention to some of the country's largest corporations. There were problems with train telegraphic equipment, but he later invented a train telegraph that did not depend on contact between the moving train and the conducting wire.
In June of 1880 a marriage license was issued to Granville and Sadie Turner in Cincinnati.[5] In 1887 Granville married Ada under assumed names of G. Taylor Silvey and Edith Albus White. [6] They divorced that same year. By 1900 he was listed as an electrical engineer, single, and living in Manhattan, New York.[7]
He died in 1910[8] and is buried in Saint Michael's Cemetery in East Elmhurst, New York.[9]
