The Pye History Project is an industrial history program to research, document and record the history of the Pye Group of Companies between 1896 and the present day. The long-term objective of the project is to establish or participate in a public museum which will adequately interpret and display the full extent of the scientific and technological discoveries and innovations which originated in Cambridge and the surrounding area. The Pye Group was always headquartered in Cambridge, England.
