A civil engineer with the railroad, he started W. E. Kingswell, Inc. in 1927. During the war, the warehouse was transformed into a provider of electronic assembly for the U.S. Armed Forces. After the war, Mr. Kingswell sold Minneapolis Honeywell and Stoker controls for boilers, later becoming a manufacturer agent.
