At that time Transistor Products was producing germanium from germanium dioxide. In his Oral History Dr Neville Fletcher recalls working for the company in the Summer of 1953. Development had begun on alloy junction power transistors. They had produced a remarkably wide range of prototype products including gold bonded diodes, point-contact and grown junction transistors and photo devices produced from germanium made by the company. These were key recruitments and together with the Bell license, formed an unhelpful exclusive dependency on Western Electric technology and a fruitful relationship with Harvard University.īy March 1953 the company had a staff of about 25 persons including consultants. Quirk was responsible for organizing and managing all manufacturing and engineering operations for transistors and crystal diodes. Mr Ed Quirk, also a Harvard alumnus, had been recruited from Western Electric, Allentown as Production Manager. Research and Development was led by Dr Richard Johnston, a recent graduate from Harvard. The purpose of the Bell Symposium was to transfer Bell’s semiconductor know-how developed over the five year period from the end of 1947 when it invented the transistor through to 1952 when it began to make licenses to its technology available to US and foreign companies.
Radio transistor 1952 license#
Transistor Products were one of some 35 licensees who had paid a one time license fee of $25,000 and who attended a Symposium hosted by Bell for eight days in April 1952. Its founding took advantage of the commercialisation of the transistor following its invention by Bell Laboratories. Transistor Products first premises were in Brighton, Boston, Massachusetts. Holt owned Scientific Specialties Corp which produced laboratory equipment. Roland B Holt, its President and former Director of the Nuclear Physics Laboratory at Harvard University headed the research.
Their rationale for entering the electronics industry is unclear. Purolator produced an extensive range of fuel and oil filters.
A brief announcement advised that a license had been obtained from Western Electric and that Scientific Specialties Co of Boston would produce specialised equipment for quality transistor manufacture. Transistor Products was incorporated mid 1952 in Rahway New Jersey as a new subsidiary of Purolator Products Inc.
