Francis Robbins Upton

Died 10 Mar 1921 (born 1852).American mathematician and physicist who, as assistant to Thomas Edison, contributed to the development of the American electric industry. Upton was the best educated of Edison's Menlo Park assistants. He was recruited by investors who felt it couldn't hurt to supplement Edison's wizardry with some advanced scientific training. He joined Edison in 1878, working at Edison's Menlo Park laboratory on mathematical problems relating to the development of the light bulb, the watt-hour meter and large dynamos. He later became a partner and general manager of the Edison Lamp Company (est. 1880). Upton's articles for Scientific American and Scribner's Monthly introduced many of Edison's inventions to the public.
