First handheld calculator invented, 1967
A Texas Instruments team, led by Jack Kilby, invents the first handheld calculator in order to showcase the integrated circuit. Housed in a case made from a solid piece of aluminum, the battery-powered device fits in the palm of a hand and weighs 45 ounces. It accepts six-digit numbers and performs addition, subtraction, multiplication, and division, printing results up to 12 digits on a thermal printer.
