Bell Labs and Bell Sound Division Thompson Ramo Wooldridge, Inc. are not associated.

Bell Sound Division was part of TRW originated in 1901 with the Cleveland Cap Screw Company, founded by David Kurtz and four other Cleveland residents.

It lasted more than a century until being acquired by Northrop Grumman in 2002.

In 1950, Simon Ramo and Dean Wooldridge worked for Hughes Aircraft, leading the development of the Falcon radar-guided missile, among other projects. They grew frustrated with Howard Hughes’ management, and formed the Ramo-Wooldridge Corporation in September 1953.

With continued backing from Thompson Products, Ramo-Wooldridge diversified into computers and electronic components, funding Pacific Semiconductors in 1954. They also produced scientific spacecraft such as Pioneer 1.

In February 1959, Jimmy Doolittle became Chairman of the Board of Space Technology Laboratories (STL), the division which continued to support the Air Force ICBM efforts.

Dean Wooldridge retired in January 1962 to become a professor at Caltech.

Simon Ramo became President of the Bunker-Ramo Corp in January 1964, a company jointly owned by TRW and Martin-Marietta for the production of computers and displays.

This reel to reel tape recorder was built in 1964. We could find no mention of Bell Sound Division manufacturing this reel tape recorder.

Thompson Ramo Wooldridge officially became TRW Inc in July 1965.

The company was #57on the Fortune 500 list of highest revenue American companies in 1986, and had 122,258 employees in 2000.

They had operations in 25 countries.
