12719 Pingré           Discovered 1991 June 6 by E. W. Elst at the European Southern Observatory.
Alexandre-Guy Pingré (1711-1796), a French astronomer, was sent by the king to the isle of Rodrigue in the Indian Ocean to observe the transit of Venus in 1761. Pingré is particularly known from his two-volume Traité historique et théorique des comètes (1783-1784).
