3.5X4.25 Vintage Glossy photograph of William Shockley with a model he's explaining. Signed by William Shockley in ballpoint ink adding a sketch of a transistor. In excellent condition.(1910-1989) William Bradford Shockley Jr. was an American physicist and inventor. He was the manager of a research group at Bell Labs that included John Bardeen and Walter Brattain. The three scientists were jointly awarded the 1956 Nobel Prize in Physics for "their researches on semiconductors and their discovery of the transistor effect".Partly as a result of Shockley's attempts to commercialize a new transistor design in the 1950s and 1960s, California's Silicon Valley became a hotbed of electronics innovation.In his later life, while a professor of electrical engineering at Stanford University and afterward, Shockley became widely known for his extreme views on race and his advocacy of eugenics.This lot came from the Jim Wiggins collection we purchased in July 2022.
