Granville Woods and Induction Telegraphy

There are some who say that the number of patents Woods obtained is at least 60, may be even much higher. But from Professor Fouché’s book, I’ve only identified 45 patents for Woods which is still a pretty awesome figure. These patents may be divided into essentially 4 technology categories: (1) induction telegraphy of which there are 8 patents; (2) electrical railways of which there are 20 patents; (3) other electrical devices of which there are 13 patents; and (4) 4 patents on “other inventions” that don’t fall into any specific category. This article focuses only the first category of inventions, induction telegraphy, for which Woods is most famous for. So why is induction telegraphy important? Well…

The Black Edison: Granville T. Woods

Granville Woods is often referred as “The Black Edison.” Woods and Thomas Edison went to court twice over what were apparently invention disputes. Both times, Woods won. There’s even a story, perhaps “folklore,” that Edison asked Woods to work for him, but Woods turned down Edison’s offer. Admittedly, Edison, with close to 1100 patents to his name, is far better known than Woods. But the parallels between these two inventive giants are striking in many respects. Both were from Ohio. Each came from very humble or modest family backgrounds. Each was primarily self-taught and highly entrepreneurial. Their scientific intellect was keen and often focused on electrical technologies. The scope of their inventive discoveries was also quite varied, and extremely prolific.
