Marie-Jeanne de Lalande
Marie-Jeanne de Lalande (* 1768 in Paris as Marie-Jeanne-Amélie Harlay, † November 8, 1832 as married Marie-Jeanne Lefrançais de Lalande) was a French astronomer.
She was the illegitimate daughter of Jérôme Lalande and at the same time the wife of his cousin Michel Lefrançais de Lalande (1776-1839). Both were Lalande's students in astronomy. De Lalande initially supported her husband in his work and worked on reducing the number of observations for Lalande's star catalog at the École Militaire observatory . Many calculations by Lalandes Abrége de navigation (1793) and in the Lalande ephemeris published annually in the Connaisance de Temps from 1794 to 1806 come from her.
In 1789 she began to work as an observer at the Collège de France with Alexandre Cassini . In 1798 she accompanied her father to the first European astronomical congress in Gotha . In 1799 she compiled a star catalog with 10,000 stars.
The Venus crater de Lalande is named after her.
