Biographical history

Joseph Jérôme Le Français de Lalande (1732-1807) was a French astronomer and writer.

Joseph Jérôme Le Français de Lalande was born on July 11, 1732, at Bourg-en-Bresse to Pierre Lefrançois and Marie‐Anne‐Gabrielle Monchinet. He went to Paris to study law, but was drawn to astronomy and became a pupil of both Joseph-Nicolas Delisle and Pierre Charles Le Monnier. At the age of twenty, Lalande was admitted to the Academy of Berlin, as well as elected as an adjunct astronomer to the French Academy of Sciences. He devoted himself to the improvement of planetary theory, and replaced Delisle as chair of astronomy in the Collège de France in Paris, a position he held for forty-six years. Lalande was also a compiler of navigational and astronomical tables and author of astronomy texts and other books on the history of mathematics and astronomy. Jérôme Lalande died on April 4, 1807.
