Double diffusion made possible, for the first time, the mass production of precise, high-performance transistors. The technique promised to be highly profitable for any organization that could master its technical intricacies. Shockley therefore quit Bell Labs and, with financial backing from Arnold Beckman, president of a prestigious maker of scientific instruments, started a company to produce double-diffusion transistors. The inventor recruited the best young minds he could find, including Noyce; Gordon Moore, a physical chemist from Johns Hopkins; and Jean Hoerni, a Swiss-born physicist whose strength was in theory. Already thinking about human intelligence, Shockley made each of his recruits take a battery of psychological tests. The results described Noyce as an introvert, a conclusion so ludicrous that it should have told Shockley something about the value of such tests. Early in 1956, Shockley Semiconductor Laboratories opened for business in the sunny valley south of Palo Alto. It was the first electronics firm in what was to become Silicon Valley.
