Jack Kilby can be rightly acknowledged as the face of modern computing, for had it not been for his invention of the integrated circuit and microchip, the computer industry wouldn’t have been what it is today. The world today is literally at the palm top, with integrated circuit and microchip meeting much of our daily needs and requirements. Before Kilby invented the integrated circuit, computers were mostly room-sized with a restricted usage. It was his discovery that transformed the machine into the size we use today. The small wonder has revolutionized the way electronic industry works and can be safely regarded as a historical discovery in computer technology. Jack Kilby’s association with science and electronics was long. Having an affinity for physics and mathematics since early on, Kilby, after completing his studies, took up job at Texas Instruments. It was while solving the problem of ‘tyranny of numbers’ that Kilby was first struck with the idea of an integrated circuit. Working along the idea, in 1958, he eventually invented the integrated circuit. For the same, he received numerous prestigious and esteemed awards and honors, including the Nobel Prize. Kilby’s other contribution include invention of thermal printer and world’s first integrated-circuit based calculator
