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.
