12715 Godin           Discovered 1991 Apr. 8 by E. W. Elst at the European Southern Observatory.
Louis Godin (1704-1760) was a French astronomer who proposed to send expeditions to the equator and the polar sea to measure an arc of one degree, in order to find out the true shape of the Earth. In 1753 he joined Condamine and Bouguer on an expedition to Peru.
