Summary[edit]
DescriptionBell telephone magazine (1922) (14755881622).jpg |
English: Photo of (left to right) John Bardeen, William Shockley and Walter Brattain, 1948. This is one of a series of publicity photos produced by Bell Labs prior to the public announcement of the invention of
the transistor (June 30, 1948). Although Shockley was not involved in the invention, and has never been listed on patent applications, Bell Labs decided that he must appear on all publicity photos along with Bardeen and Brattain. Shockley's Nobel Prize contribution - theory of a junction transistor - was separate from the Bardeen-Brattain work. Русский: Джон Бардин, Уильям Шокли, Уолтер Браттейн. Рекламное фото Bell Labs, приуроченное к публичному объявлению об изобретении первого (точечного) транзистора 30 июня 1948 года. Шокли не участвовал в изобретении, но компания решила, что он должен присутствовать на всех официальных фото изобретателей рядом с Бардином и Браттейном.
