/ref> Warren founded Warren Telechron Company in 1912 which later was acquired by General Electric in 1943. Warren was noted as the "father of electric time". Telechron went out of business in 1992. Just between 1916 and 1926 the company sold 20 million clocks. 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. Warren's early career started as an engineer for Nathaniel Lombard, designing water-driven machinery for the N. Lombard Improved Governor Co. in Roxbury, MA. He worked his way up to Plant Superintendent, eventually purchasing the company in 1937, at which time it was renamed Lombard Governor Company. He was owner and president of Lombard up until his death in 1957.
