Henry Ellis Warren (May 21, 1872 – September 21, 1957) was an American inventor credited with invention of the first synchronous electric clock which kept time from the oscillations of the power grid in 1918 as well as with 134 other inventions. [1][2][3][4][5] Warren founded Warren Telechron Company in 1912 which later was acquired by General Electric in 1943.[1] Warren was noted as "the father of the electric time".[5] Just between 1916 and 1926 the company sold 20 million clocks.[1] The clocks remained popular into the 1950s. In 1940 he also invented the "singing clock" which instead of a pendulum had a vibrating metal string.[1]
