At the Dusseldorf Radio Fair in 1953, the German firm Intermetall unveiled what was probably the world's first transistor radio, more than a year before Texas Instruments claimed that milestone. The radio's amplifier circuit was built around four point-contact transistors made by Intermetall, which Herbert Matare and businessman Jakob Michael had founded in 1952. Intermetall was the first European company with a production program for semiconductor diodes and transistors.
