Integrated circuit pioneer Jack Kilby has died, aged 81.
While working at Texas Instruments in 1958, Kilby built the first electronic circuit in which all the components were fabricated onto a single piece of material.
This was promoted as the world’s first integrated circuit. The microchip was demonstrated later that year.
Before integrated circuits came along electronics engineers soldered the various parts of a circuit together. Intel co-founder Bob Noyce developed a similar version of the integrated circuit just after Kilby.
Kilby’s work eventually won him a Nobel Prize for physics in 2000.
Kilby retired from Texas Instruments in 1970 but continued to serve the firm as a consultant. He was also a professor at Texas A&M University.
