So came into being the transistor destined to be the vacuum tube Vanquisher. Compel d man looked for new device that would bring limitation to its demise. Vacuum tubes with hot heater of high wattage wouldn’t work without high voltage. For their creation, maintenance and destruction had put upon him severe technological limitation. Mankind with vacuum tubes was buried under the tyranny of colossal power consumption.

Transistor inventors Bardeen, Brattain (standing L-R), and Shockley (seated) on the cover of Electronics magazine in Sept 1948. The team demonstrated the discovery a week later on December 23, often considered the date the transistor was invented.īell Labs publicly announced the device at a Jpress conference, where a spokesman claimed that “it may have far-reaching significance in electronics and electrical communication.” The voltage on one contact modulated the current flowing through the other, amplifying the input signal up to 100 times. They applied two closely-spaced gold contacts held in place by a plastic wedge to the surface of a small slab of high-purity germanium. It wasn’t until Decemthat the first successful test of their semiconductor amplifier occurred. Bardeen and Brattain’s first point-contact transistor.
