Eureka Electric was founded in McCordsville Indiana, but moved to Chicago in 1898 to scale up production (as the independent telephone movement exploded, Chicago quickly became the manufacturing hub for anti-monopoly phone equipment). In 1902 Eureka merged with the Advance Electric Company and relocated its manufacturing plant out of Chicago to Genoa, Illinois. In 1907 the company was reorganized and renamed the Cracraft-Leich Electric Company (combining Eureka's lineage with engineer Oscar M. Leich).
