Lefschetz, Solomon(1884–1972) mathematician; born in Moscow, Russia. He emigrated to America to work as an engineer (1905). Obtaining a Ph.D. (1911), he taught longest at Princeton (1924–53) and chaired its mathematics department (1945–53). Best known for linking topology to algebraic geometers, he also contributed to fixed-point theory and differential equations. Editor of Annals of Mathematics (1928–58), editor/founder of the Journal of Differential Equations, he was an author of math texts and founded a math center (1957) that was later moved to Brown University and named the Lefschetz Center for Dynamical Systems.
Born Sept. 3, 1884, in Moscow. American mathematician.
Lefschetz was appointed a professor at Princeton University in 1924. He is the author of studies on algebraic geometry (theory of multidimensional algebraic manifolds involving substantial application of topological methods). In topology, Lefschetz, together with H. Hopf, created the general theory of the intersection of cycles in manifolds and is the originator of the algebraic theory of continuous mappings.
