Integrated Circuit Co-Inventor Kilby is Born
Jack Kilby is born in Jefferson City, Mo. After several years of study at the University of Illinois and University of Wisconsin, Kilby began work at Texas Instruments Inc., where he invented the integrated circuit in 1958. With that invention, he proved that resistors and capacitors could exist on the same piece of semiconductor material.
The first integrated circuit consisted of a sliver of germanium with five components linked by wires. It was Robert Noyce at Fairchild Semiconductor, however, who made Kilby's invention practicalboth men are thus credited with the invention of the IC.
