“The integrated circuit was built by Texas Instruments in 1958,” Heritage Auction Nature and Science Director Craig Kissick says.

Tom Yeargan was a technician who worked with Texas Instruments engineer Jack Kilby. Kilby’s design earned him the Nobel Prize in Physics. Kilby mentioned Yeargan’s name during his speech for winning the Nobel Prize.

“This is a germanium wafer with some wires coming off it. It has a silicon chip,” Kissick says.

The microchip is one of the early prototypes that led to the creation of the modern integrated circuit. In turn, the semiconductor technology became the basis for cell phones and personal computers.

The Yeargan family decided to auction the chip off and hope it will be put on display.
