Karl Daniel

Karl Daniel (born February 22, 1905 in Jünkerath , Daun district , Eifel ; † July 31, 1977 in Cologne-Porz ) was a German entrepreneur.

Life

Daniel studied mechanical engineering and electrical engineering at the Polytechnikum Friedberg, today's Technische Hochschule Mittelhessen, Campus Friedberg . He later received his doctorate as Dr. rer. pole. In the 1930s, he worked on the development of a telephone - answering machine , which, however, because of the restrictive admission policy of the Reich Post did not sell. The brand name "Tefi" comes from this; "Te" stands for telephone, "Fi" for film. In 1936 Karl Daniel founded Tefi-Apparatebau Dr. Daniel KG . In the same year he showed his endless record at an exhibition . From 1946 to 1949 he manufactured detector receivers and radios in the Porz plant .

Girls were also trained in radio and television technicians at the Tefifon company . In 1957, Karl Daniel left the company. In 1976 he was awarded the Federal Cross of Merit on ribbon.
