What Happened on September 11th

The first public demonstration of remote computation occurs during a meeting of the American Mathematical Society at Dartmouth College. Bell Laboratories researcher George Stibitz set up a terminal that allowed conference attendees to perform remote calculations over telephone lines with Bell Labs’ Complex Number Calculator in New York City. Stibitz had first tested the connection on September 9, an event memorialized by a plaque in front of McNutt Hall at Dartmouth College.
