Several Alabamians have been granted patents for inventions of “useful” devices. (The requirements for a patent include the invention’s being “useful.”) The most well-known local inventor is Mary Anderson from Birmingham. She invented the windshield wiper or “Window Cleaning Device” in 1903. Its number is #743,801.
George Washington Carver is probably the most famous inventor associated with Alabama. Credited with hundreds of agricultural products, the Tuskegee professor only had three patents, none of which is for peanut butter. One is “Paint and Stain and Process of Producing the Same,” #1,541,478, patented in 1925.
A surprising patent holder is Erskine Ramsay, one of the founders of Birmingham’s steel industry. He was granted several patents dealing with steel production and mining, such as “Revoluble Car Dumping Structure” (1902) and “Means for Checking and Sampling Miners’ Coal” (1916). These numbers are #701,764 and #1,191,227, respectively.
Another extremely significant Alabama “import” inventor was Wernher von Braun, developer of the American space program. Among his many achievements is a patent for a “Rocket-Propelled Missile,” #2,967,393, granted in 1961.
Inventors come from a variety of backgrounds, from the “real” scientists, like Thomas Edison, to performers, such as Michael Jackson, to children, like Alexia Abernathy (she invented a “spill-resistant bowl” when she was 11 years old). Take a look at some of the dozens of books in BPL’s collection on inventions and inventors; you might be inspired to invent something yourself.
