Title:
Bowmar Brain Calculator
Description:
The Bowmar Instrument Corporation was formed in Fort Wayne in 1951 by a former employee of the Farnsworth Television Company, Edward White, and his wife Joan. In 1971, the "Bowmar Brain" calculator was the first handheld calculator introduced to the market. It allowed the Bowmar Instrument Corporation to regain the lead against Japanese calculator manufacturers, although Texas Instruments was their main competitor. Bowmar was unprepared for the huge popularity of the new item and left the consumer market to pursue government contracts. This Model 90505 calculator, known as the MX50 Personal Calculator with "Omni—Constant Register" has an AC adapter on the side, operating instructions on the back and its own carrying case. The familiar LED (low energy diode) display still common today.
