DEATHS ELSEWHERE

January 28, 1995

Albert W. Tucker, 89, former chairman of the mathematics department at Princeton University and developer of the "Prisoner's Dilemma" paradox, died of pneumonia Wednesday. He was known among mathematicians for his work in linear programming and game theory. He created the Prisoner's Dilemma in 1950 to illustrate the difficulty of non-zero-sum games to a group of psychologists at Stanford University. A non-zero-sum problem is one in which one contestant's win is not necessarily a loss for the other contestant. In the paradox, two partners in crime are faced with having to decide whether to confess or not.

William D. "Willie the Rat" Cammisano, 80, former Kansas City, hTC Mo., mob leader, died Thursday of multiple organ failure related to lung disease. In testimony before Congress in 1980, Fred Harvey Bonadonna, son of a mobster, said Mr. Cammisano got his nickname "because he killed people and stuck them in the sewers so the rats could eat them." Mr. Cammisano, however, always contended the actual nickname was "Willie Rats," earned as a child when he lent his dog to rid houses of rats.
