sep 30, 1958 - Jack Kilby Invented the Integrated Circuit

Description:

Jack spent the summer working on the problem in circuit design that was commonly called the "tyranny of numbers", and he finally came to the conclusion that the manufacturing of circuit components en masse in a single piece of semiconductor material could provide a solution. . He showed them a piece of germanium with an oscilloscope attached, pressed a switch, and the oscilloscope showed a continuous sine wave, proving that his integrated circuit worked, and hence he had solved the problem.
