Transistor History
I have been interested in collecting artefacts of early technology for many years and post the 50th anniversary of the invention of the transistor and the explosion of published material celebrating the early years of the transistor have become interested in collecting early transistor memorabilia. Unlike other early technologies I have collected I am part of the transistor generation having been born the year the point contact transistor was announced by Bell Laboratories and having purchased as a teenager some real examples of early transistor technology and used them to build radios and other electronics.

Professionally I am interested in the commercialisation of research and the story of the development of semiconductor technology is a remarkable example of this.
