How did George Stibitz shape digital computing and networks?

George Stibitz was a mathematician at Bell Telephone Laboratories who made foundational contributions to early computing and terminology. In 1940, he created the first computer network by connecting a terminal at Dartmouth College to his Complex Number Calculator in New York. Additionally, he popularized the term digital in 1942 to describe the fast electrical pulses emitted by a device designed to aim anti-aircraft guns.

What we know

• Mathematician George Stibitz of Bell Telephone Laboratories used the word digital in 1942 to describe fast electrical pulses from a device used for aiming and firing anti-aircraft guns. [2]
• George Stibitz created the first computer network in 1940 by connecting a terminal at Dartmouth to his Complex Number Calculator at Bell Labs in New York. [3]
• The word digital comes from the same Latin source as digitus, referring to fingers used for counting. [2]
