On September 12, 1958, Mark Shepherd witnessed the demonstration of the integrated circuit by Jack Kilby and what other individual?
Jack Kilby Jack St. Clair Kilby (November 8, 1923 – June 20, 2005) was an American electrical engineer who took part (along with Robert Noyce) in the realization of the first integrated circuit while working at Texas Instruments (TI) in 1958. He was awarded the Nobel Prize in Physics on December 10, 2000. To congratulate him, American President Bill Clinton wrote, "You can take pride in the knowledge that your work will help to improve lives for generations to come."
Esther M. Conwell Esther Marley Conwell (May 23, 1922 – November 16, 2014) was a pioneering American chemist and physicist who studied properties of semiconductors and organic conductors, especially electron transport. She is best known for the Conwell-Weisskopf theory which elucidates how electrons travel through semiconductors, an accomplishment that helped revolutionize modern computing.
