11763 Deslandres           Discovered 1960 Sept. 24 by C. J. van Houten and I. van Houten-Groeneveld on Palomar Schmidt plates taken by T. Gehrels.
Henri Deslandres (1853-1948) was a French astrophysicist and observatory director. An independent inventor of the spectroheliograph, he investigated molecular spectra in the laboratory and observed the solar chromosphere.
