We just learned that David Erbach has died. A long time go player, and former editor of the publication Computer Go, Erbach taught Computer Science at Western Kentucky University until his retirement in 2014. “Dave was part of the wave of early computer scientists who made the first tentative attempts to program a computer to represent and then to play go,” says former AGA president Terry Benson. Erbach was previously head of the Computer Science department at Purdue University-Fort Wayne and the Business Computing department at the University of Winnipeg. In addition to go, he loved model airplanes and was, with his father, a competitive member of the Academy of Model Aeronautics. He was also a keen pianist. He died of prostate cancer in September 2016, at the age of 69.
