Brush Development Company
Brush Development Company was a manufacturer of audio, phonographic products and magnetic recording technologies located in Cleveland, Ohio. It was absorbed into Clevite in 1952.
History
[edit | edit source]The business was founded in 1919 by Alfred L. Williams as Brush Labs to develop products that used piezoelectric crystals.[1] Associates spun off the Brush Development Company in 1930, with piezoelectric phonograph pickups as their main product.[2] Later, it began manufacturing wire recorders, microphones, and speakers.
During World War II, Vice President for Research Dr. Semi Joseph Begun[3] was awarded a contract from the US National Defense Research Council for research on a substitute for stainless steel wire used in wire recorders by the military.[1]
Brush was instrumental in convincing the Minnesota Mining and Manufacturing Company - 3M to research recording tape.[3] Its successful lab work resulted in a commercial product, the first in its long series of magnetic recording tape and other media products.[4] Post-war, Brush manufactured a dictation recorder in 1946, and released the first USA built tape recorder in 1947 with the Brush Soundmirror. In 1950, Brush built the Model BL-206 and BL-216 Multichannel Oscillographs, and associated Model BL-932 DC Amplifiers.[1][2]
In 1952, Brush Development Company merged with the original Brush Labs and the Cleveland Graphite Bronze company to create Clevite. Audio products continued to be sold under the Brush trademark until 1960.[1]
The Clevite company was absorbed by Gould-National Batteries in 1969.[2][5]
