The opening as it read in 2010
Aviezri Siegmund Fraenkel ( ) is an Israeli mathematician , who has made notable contributions to combinatorial game theory .1He was born in Munich on June 7, 1929, but his family moved to Switzerland soon after. In 1939 his family moved once more to Jerusalem . Fraenkel received his Ph.D. in 1961 from the University of California, Los Angeles . He was a recipient of the 2005 Euler Medal together with Ralph Faudree . On December 5, 2006, he received the "WEIZAC Medal" from the IEEE as a member of the team who built the WEIZAC , one of the first computers in the world. His research also delves into computational complexity , as it is important to study the complexity of algorithms which solve games.2
