Short Summary
Granville T. Woods was an African American inventor and engineer, renowned for his groundbreaking work in the field of electrical engineering and railways. With over 50 patents to his name, he made significant contributions to the development of communication and safety systems for railroads. His most notable invention was the induction telegraph, which greatly enhanced train communication and safety. Woods is often celebrated as one of the most prolific African American inventors of the late 19th and early 20th centuries.
Early Life & Education
Born on April 23, 1856, in Columbus, Ohio, Granville T. Woods was the second of three children. His parents were free African Americans, and his father worked as a sawyer. At a young age, Woods showed an interest in mechanics and engineering. He attended school until the age of ten, after which he worked to help support his family. Despite limited formal education, Woods continued to study electronics and engineering on his own, taking correspondence courses and attending evening classes. His early experiences working in railroad machine shops and steel mills laid the foundation for his future innovations.
Career Highlights
Woods began his professional career as an engineer on the British steamer Ironsides, where he gained invaluable hands-on experience. In 1880, he moved to Cincinnati, Ohio, and established a company to develop electrical apparatus. His career flourished with the invention of the "telegraphony," a device that combined a telephone and telegraph. Woods' most significant contribution came in 1887 with the invention of the induction telegraph, which allowed for communication between moving trains and railway stations. This invention was pivotal in enhancing railway safety and efficiency, earning him the nickname "The Black Edison."
