In 1951, just four years after the invention of the transistor by Bell Laboratories, the Allentown Plant was opened to manufacture the first transistors. Jack Morton was assigned to develop transistors for manufacture. He had been responsible for inventing and providing the military with microwave components during WWII and knew how to get an idea from the lab, into production, and into the field. He established a system of branch labs at several Western Electric plants, consisting of teams of Bell Labs scientists and engineers focused on production engineering and acting as liaison with their colleagues back in Murray Hill. Morton fine-tuned this approach at the new Western Electric plant in Allentown, Pa., which produced electronic devices and components for the Bell System. He set up a Bell Labs semiconductor development group there and put Eugene Anderson in charge.
