Douglas Clark, a professor of computer science at Princeton University, demonstrates a functioning Turing machine that was built by his father Wesley A. Clark and Bob Arnzen at Washington University in Saint Louis in the 1970s. Wes Clark is co-creator of the first personal computer. The machine currently resides in Doug Clark's office in Princeton.
The Turing machine is a theoretical concept named for Alan Turing, considered the father of computer science. Turing was a graduate student at Princeton during the 1930s.
