The Transistor: perhaps the most important development of the 20th century The transistor is the fundamental building block of modern electronic devices. First practically implemented in 1947 by American physicists John Bardeen, Walter Brattain, and William Shockley, the transistor revolutionized the field of electronics, and paved the way for smaller and cheaper radios, calculators, and computers, among other things. The transistor is on the list of IEEE milestones in electronics, and Bardeen, Brattain, and Shockley shared the 1956 Nobel Prize in Physics for their achievement. https://en.wikipedia.org/wiki/Transistor http://i0.wp.com/sostrenews.com/wp-content/uploads/2015/10/us__en_us__ibm100__603calc__603_vacuum__620x350.jpg http://www.wylie.org.uk/technology/semics/Ediswan/Ediswan.htm
