by Eugene Armstead on Feb.21, 2010, under Black History Month Project
FOX21 News highlights Black History month today with a look at Granville T Woods, also known as the “Black Edison.” In 1901, Woods developed what is known as his most important invention… the power pickup device, what we know today as the “third rail” used by most subways in large cities accross the country. By the time of his death in 1910, Woods had some 60 patents, many of which are still in use today with many major manufacturers of electrical equipment.
