He worked for the Westinghouse Electrical and Manufacturing Company in East Pittsburgh, Pennsylvania for half a century. ==Early life== Frank Conrad was born May 4, 1874 in Pittsburgh, Pennsylvania, the son of Herbert M. Conrad, a railroad mechanic, and Sadie Conrad. His formal education ended with 7th grade, however in 1928 his work would be recognized with an honorary Doctor of Science degree from the University of Pittsburgh. Conrad began employment at the Westinghouse Electrical and Manufacturing Company at age 16, and at 23 began working in Westinghouse's Testing Department, where his inventions included, in 1897, the circular-type watt-hour meter. (In 1937, it was estimated that 30 million of these units were in use.)〔"Radio—Trick Watch: First Radio Broadcasting Followed Founder's Time Wager in Pittsburgh", ''Literary Digest'', March 13, 1937, page 19.〕 In 1904, the company appointed him General Engineer, and he was promoted to Assistant Chief Engineer in 1921. Conrad was awarded more than 200 patents internationally throughout his life.〔("A Bibliography of Frank Conrad" ), David W.
