Dietrich Gunther Prinz (March 29, 1903 – December 1989)[1] was a computer science pioneer, notable for his work on early British computers at Ferranti, and in particular for developing the first limited chess program in 1951.[2][3]
He had some Jewish parentage and left Germany to join GEC in Wembley as a researcher into valve technology. During the Second World War, he was interned in Canada,[4] and when he returned he worked first in Leeds for the Bowen Instrument Company.[5] Prinz became a British citizen in 1947.[6]
Prinz was recruited to the Ferranti factory at Moston, Manchester, in 1947 by Eric Grundy who was setting up a team to study the potential uses of electronic computers.[5] After Ferranti was awarded a contract to build a production version of the Manchester computer, which would become the Ferranti Mark 1, Prinz worked closely with the University of Manchester team.[5]
Prinz wrote a manual for the Ferranti Mark 1 which was much clearer than the notoriously opaque first manual written by Alan Turing.[4][10] He remained a mainstay of the programming department for thirty years.[5] He spent some time in Italy supporting Ferranti installations there.
Prinz had learned programming on the Mark I from seminars led by Alan Turing and Cicely Popplewell.[11] Influenced by them, and later by other colleagues including Donald Michie, Christopher Strachey and Donald Davies,[12] he came to see chess programming as "a clue to methods that could be used to deal with structural or logistical problems in other areas, through electronic computers".[11] Turing had also worked out an algorithm for playing chess, but Prinz's work was independent of this.[13] The Mark I was inadequate to play a complete game of chess and Prinz concentrated on the endgame. In November 1951, his program on the Ferranti Mark I first solved a Mate-in-two problem.[14]
A description of the program was included in the 1953 book Faster Than Thought.[14]
Prinz also developed simple logical machines with the Manchester University philosophy lecturer Wolfe Mays[14] and also worked in the area of computer music.[4]
He died in December 1989.
Personal life
Prinz was married and had two children, Jonathan Franklin Prinz and Daniela Prinz.[6]
