 Amrad, American Radio & Research Corporation, was based in Medford Hillside,
Massachusetts and was founded in 1915 with funds from J. Pierpont Morgan. The company's
first manager, Harold James Power, was an amateur radio enthusiast and built a research
laboratory. In 1916, Amrad made its first broadcast to J. Pierpont Morgan Jr., who
was aboard the ocean liner "Philadelphia."
Amrad received orders for military radio equipment during World War I, but discontinued
these orders after the war ended. To keep the company afloat, Amrad produced items
such as electric egg beaters and cigar lighters. In 1919, Amrad was awarded a contract
to make 400 SE1420 receivers, and it began advertising components for amateur radio
enthusiasts. Amrad's crystal set was a popular product and helped the company during
difficult times.
In 1923, the company joined the Independent Radio Manufacturers Inc. and acquired
the rights to the Hazeltine neutrodyne invention. However, Amrad went into receivership
in April 1925 and was purchased by Crosley Radio Corp. for $39,000. Amrad also made
gaseous rectifier tubes, including the S tube developed by Charles Grover Smith,
which was used for transmitter voltage. Amrad's patents for the gaseous rectifier
tubes were eventually sold to Raytheon.
