Euler's Correspondence with Joseph Jerome Lefrancois de Lalande

Lalande (1732-1807) was a French astronomer who served as Professor of Astronomy at the College de France from 1762-1795, a period encompassing the whole of Euler's second Saint Petersberg period. Early in his career, Lalande worked with Lacaille to take observations on the paralax of the moon, the two of them working from Berlin and South Africa, respectively.

Lalande devoted a large part of his working life to preparing a catalog of 47,000 stars, which he published in 1801. He was also a great popularizer of astronomy. It was Lalande who wrote all of the astronomy articles in the great Encyclopedie.
