1947 Dec 23, John Bardeen and Walter Brattain of AT&T Bell Labs in Murray Hill, New Jersey, unveiled what was soon to be called the transistor, short for the electrical property known as trans-resistance, which paved the way to a new era of miniaturized electronics. The device was improved by William Schockley as a junction transistor. All 3 received a Nobel Prize in 1956. The events are described in the 1997 book by Michael Riordan and Lillian Hoddeson: “Crystal Fire: The Birth of the Information Age."
