7720 Lepaute           Discovered 1960 Sept. 26 by C. J. van Houten and I. van Houten-Groeneveld on Palomar Schmidt plates taken by T. Gehrels.
Named after Nicole-Reine Lepaute (1723-1788), extraordinarily talented French mathematician. The astronomers Lalande and Clairaut sought her help for the computations needed to predict the 1759 return of comet 1P/Halley. Lepaute's computations for the annular eclipse of 1764 were used throughout Europe. Unfortunately, years of calculation left her nearly blind.
