How did George Stibitz contribute to anti-aircraft gun tech?

George Stibitz was a Bell Labs researcher and pioneer of digital computing who applied his work on electromechanical relays to military technology. In 1942, he used the word "digital" in reference to the fast electrical pulses emitted by a device designed to aim and fire anti-aircraft guns. His foundational developments helped shape early digital computing systems during the 1930s and 1940s.

What we know

• George Stibitz worked as a researcher at Bell Labs and is recognized as a pioneer of the modern digital computer. [1, 2]
• In the 1930s and 1940s, Stibitz worked on implementing Boolean logic digital circuits using electromechanical relays as switching elements. [2]
• In 1942, mathematician George Stibitz used the word "digital" to describe fast electrical pulses in a device created to aim and fire anti-aircraft guns. [3]
