Much of the historical research on the development of the semiconductor industry has focused on the USA. This is somewhat unfair to a number of world-class research laboratories elsewhere in the world. Follow the links on this page to find out more about them.
At the time of the invention of the transistor by Bell Laboratories, two English electrical giants had strong research interests in the field:
Shortly after the invention, another English company, albeit wholly owned by Philips in the Netherlands, decided to enter the market and quickly came to dominate it:
However, in the UK there seems to have been another, limited, outlet for (possibly recycled) Philips/Mullard transistors:
In the UK, as in the USA, a number of other companies made transistors for a few years but ultimately vanished:
In addition, the US company
had a substantial manufacturing facility in Bedford, England, making germanium and silicon devices in series unique to Europe.
In the UK military/government sector, one company was pre-eminent:
On mainland Europe, germanium transistors were made in:
Further afield, germanium transistors were made in:
The early development of the semiconductor industry outside the USA is a particular interest of mine. Please if you know anything about this subject.
