Sheldon Roberts

Cornelius Sheldon Roberts (born October 27, 1926 in Rupert , Vermont , † June 6, 2014 in McMinnville , Oregon ) was an American metallurgist . In the early stages of semiconductor electronics, he was an employee of William B. Shockley and a member of the Traitorous Eight (German "The Verräterischen Acht").

life and work

In 1948 he obtained a bachelor's degree in metallurgy from the Rensselaer Polytechnic Institute, followed by a master’s degree in 1949. After his doctorate (1952, Massachusetts Institute of Technology , MIT) he worked in the Naval Research Lab and at Dow Chemical in research.

Some time later (1956) he took a position in William B. Shockley's newly formed research group at Shockley Semiconductor Laboratory , a division of Beckman Instruments in Mountain View, Santa Clara County, California . But this working group did not last long. As early as 1957, eight key employees left the research laboratory in a dispute with Shockley. These eight, including Roberts, were referred to as the Traitorous Eight (German "Die Verräterischen Acht") and founded the company Fairchild Semiconductor after their departure . At Fairchild, Roberts was responsible for the production of silicon crystals . Later he founded with Jean Hoerni and Jay Last , the company Amelco (now Teledyne ).
