In 1929, the English company Murphy Radio has been founded by Frank Murphy and E. J. Power; the company quickly turned into a vivid manufacturer of consumer radios and employed 2000 employees, F. Murphy left the company in 1937.
In WWII, Murphy developed a small portable manpack transceiver, the Wireless Set No. 38, for the British armed forces. In the following years, Murphy stepped into production of commercial and military communications equipment, one of the famous sets is the B40 receiver mainly used by the Navy.
After having made the first experiences in pre-war years, Murphy developed television sets and did stay in business until the seventies.
