Jack St. Clair Kilby was an American electrical engineer who took part in the realization of the first integrated circuit while working at Texas Instruments in 1958. He was awarded the Nobel Prize in physics in 2000. He worked on the problem in circuit design that was commonly called the “tyranny of numbers” and finally came to the conclusion that manufacturing the circuit components en masse in a single piece of semiconductor material could provide a solution. He showed that 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 thus solved the problem.
