Delambre, Jean Baptiste Joseph

 

Born Sept. 19, 1749, in Amiens; died Aug. 19, 1822, in Paris. French astronomer, geodesist, and metrologist.

In 1792, Delambre became a member and in 1803, secretary of the mathematics section of the Paris Academy of Sciences. Together with P. Mechain he took part (1792–97) in the measurement of the meridian arc from Dunkirk to Barcelona, which served as the basis for the establishment of the metric system of measures. Delambre compiled tables of the apparent motions of the sun, the large planets, and Jupiter’s satellites. He improved methods of astronomical computation and wrote a six-volume history of astronomy.
