We are saddened to announce that Jan Strooker passed away on August 16, 2014. Jan Strooker was born 29 September 1932 in Rangoon. He was professor in Algebra at Utrecht University. In the seventies and eighties he was a driving force behind the study of algebraic K-theory in the Netherlands. Later his interest moved to “Homological questions in commutative algebra”, as witnessed by his book of that title.
