Granville T. Woods: The Black Edison

maxresdefault

To me, he isn’t the Black Edison; he is Granville T. Woods, one of the most important inventors in the 19th and 20th century. 

By the time of his death, on January 30, 1910, in New York City, Granville T. Woods had invented 15 appliances for electric railways. received nearly 60 patents, many of which were assigned to the major manufacturers of electrical equipment that are a part of today’s daily life.

Lewis Latimer: Carbon Filament

lewis2blatimer

 

Latimer’s talents were well-matched to the post-Civil War period, which saw a large number of scientific and engineering breakthroughs. Latimer was directly involved with one of these inventions: the telephone. Working with Alexander Graham Bell, Latimer helped draft the patent for Bell’s design of the telephone. He was also involved in the field of incandescet lighting, a particularly competitive field, working for Hiram Maxim and Thomas Edison.

Latimer’s deep knowledge of both patents and electrical engineering made Latimer an indispensible partner to Edison as he promoted and defended his light bulb design. In 1890, Latimer published a book entitled Incandescent Electric Lighting: A Practical Description of the Edison System. He continued to work as a patent consultant until 1922.
