In Memoriam: Leon Green

Leon Green, long-time professor of mathematics, died on Aug. 17, 2009. He was 83.
Born in Passaic, New Jersey, Green earned his bachelor's degree in mathematics from Harvard in 1948, followed by a master's degree in mathematics in 1949, and a Ph.D. in mathematics in 1952, both from Yale University. Prior to joining the University of Minnesota faculty in 1953, Green taught freshman calculus at Princeton University and Yale University.

At the University of Minnesota, Green became a recognized leader in differential geometry and helped to build the School of Mathematics' strength in geometric analysis. His research interests focused on differential geometry, dynamics, and Lie theory. A member of American Math Society, he authored numerous papers, and presented at conferences worldwide, including the International Mathematical Union.

Green retired from active teaching in 1998 and served as professor emeritus of mathematics for the School of Mathematics until his death.
