Via The Pontiff, noted mathematician Israel Gel’fand has passed away at age 96. He was truly a remarkable mathematician who took an interest in mathematics education. In fact he often let his research and teaching influence each other as described here (quoting from two written papers):
One of the characteristic features of Israil Moiseevic’s activities has been the extremely close bond between his research work and his teaching. The formulation of new problems and unexpected questions, a tendency to look at even well known things from a new point of view characterises Gelfand as a teacher, regardless of whether at a given moment he is holding a conversation with schoolchildren or with his own colleagues.
In 1994 he was awarded a MacArthur “Genius Award” for his work in mathematics education, particularly in relation to correspondence education.
