作者简介 Roger Lyndon, born on Dec.18,1917 in Calais (Maine, USA), entered Harvard University in 1935 with the aim ofstudying literature and becoming awriter. However, when he discoveredthat, for him, mathematics requiredless effort than literature, he switchedand graduated from Harvard in 1939.After completing his Master s Degreein 1941, he taught at Georgia Tech,then returned to Harvard in1942 and there taught navigation topilots while, supervised by S. MacLane, he studied for his Ph.D.,awarded in 1946 for a thesis entitled The Cohomology Theory ofGroup Extensions.Influenced by Tarski, Lyndon was later to work on model theory.Accepting a position at Princeton, Ralph Fox and Reidemeister svisit in 1948 were major influencea on him to work in combinat-orial group theory, in 1953 Lyndon left Princeton for a chair at theUniversity of Michigan where he then remained except for visitingprofessorships at Berkeley, London, Montpellier and Amiens.Lyndon made numerous major contributions to combinatorialgroup theory. These included the development of "small cancellationtheory", his introduction of"aspherical" presentations of groupsand his work on length functions. He died on June 8, 1988.
