WHO PUT THE NAMES ON BRITISH TRANSISTORS
Posted by STEVE M on
The early 1950s to the late 60's were a period when many British manufacturers (there's a novelty....) made semiconductors.

Posted by STEVE M on
Indeed there were! Rohde and Schwarz, that paragon of exquisite German engineering and I am fortunate enough to own one of their EK-07 receivers and a CAQ small clock frequency standard.

In August 1933, the Physikalisch-Technisches Entwicklungslabor Dr. Rohde & Dr. Schwarz (known as PTE) started in business. The fledgling business grew such that in 1937, the small laboratory moved into a former bakery on Tassiloplatz, in Munich. From just two young PhD engineers, the copmpany now employed 35 workers and offered 24 different...
