Lewis B. Stillwell

Lewis Buckley Stillwell was an American electrical engineer, born March 12, 1863 in Scranton, Pennsylvania and died January 19, 1941 in Baltimore, Maryland, who worked on the practical problems of generating, distributing and using electrical power as the technology scaled up in the late nineteenth and early twentieth centuries. He earned his electrical engineering degree from Lehigh University in 1885, invented the Stillwell voltage regulator and a time-limit circuit breaker used to protect power systems, and served as president of the American Institute of Electrical Engineers from 1909 to 1910. In 1935 he received the AIEE Edison Medal for what its citation called his distinguished engineering achievements and pioneer work in the generation, distribution and utilization of electric energy, was later inducted into the IEEE Electrical Engineering Hall of Fame, and was elected to the National Academy of Sciences in 1921. His papers, covering the years 1886 to 1939, are held at Princeton University Library.
