Named in memory of Joseph-Jerôme Lefrançais de Lalande (1732-1807), famous French astronomer who computed many useful tables for practical astronomical work and authored many papers and textbooks. After some years as an assistant to Delisle, Le Monnier and Lacaille {see planet (9135)}, Lalande went to Berlin in order to prepare measurements for determining the lunar parallax. He was a member of the Berlin and Paris academies of science and was editor of many volumes of the almanac Connaissance des temps during 1760-1776 and 1794-1807. His monumental Bibliographie astronomique (1802) has lasted for two centuries. (M 34350; M 34385)
