led to a scientific dispute. In 1767 he sailed to the Baltic with Charles Messier to test marine chronometers. Two years later he joined a successful expedition to Haiti to observe the Venus transit of 1769. In 1771 he took part in the scientific mission of the frigate Flore, under Lieutenant Verdun de la Crenne, along with Borda. The Pingré crater on the moon is named after him, as is the asteroid 12719 Pingré. Death Pingré was left impoverished upon the suppression of his monastery in the French Revolution. He was able to continue publishing his work until his death in 1796, however, through the support of fellow astronomer, Jérôme Lalande, who obtained for him a grant of 3,000 francs from the National Assembly.
