Rolm Company

Defunct American computer and telecommunications manufacturer

ROLM Corporation was a Silicon Valley technology company founded in 1969 by four electrical engineers: Gene Richeson, Ken Oshman, Walter Loewenstern, and Robert Maxfield. The company is best known for creating a computerized telephone switching system. Their initial product was the first portable, off-the-shelf ruggedized computer for the U.S. military. In 1973, the company later expanded into telecommunications with the development of the ROLM CBX, a computerized telephone switching system. ROLM’s "Great Place to Work" (GPW) culture became a model for other companies. ROLM was acquired by IBM in 1984.
