(26909) Lefschetz Main-belt Asteroid
Discovered on 24 April 1996 by P. G. Comba at Prescott.
Solomon Lefschetz (1884-1972), professor at Princeton University, made important contributions in algebraic geometry and algebraic topology. As a result of war work he became an expert on non-linear differential equations and control theory and made Princeton a leading center in those disciplines.Naming citation (20011130/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
