Bowmar Instrument Corp

Bowmar Instrument Corp. was founded in Fort Wayne, IA in 1951 by Edward and Joan White and grew as a supplier of light emitting diode (LED) semiconductor displays. The company expanded into the production of handheld calculators in 1971. Selling under its own brand name – the Bomar Brain – and private label manufacture for Craig, Sears, and others, in the mid-1970s Bomar was one of the world's largest suppliers. A casualty of the calculator price wars, the company exited the business in 1976 to concentrate on government and industrial contracts.
