11772 Jacoblemaire           Discovered 1973 Sept. 29 by C. J. van Houten and I. van Houten-Groeneveld on Palomar Schmidt plates taken by T. Gehrels.
Jacob Le Maire (1585-1616) was a Dutch explorer who, together with C. W. Schouten, discovered parts of the Tierra del Fuego archipelago and a passage from the south Atlantic to the Pacific known as the Straits of Le Maire, which crosses Cape Horn at the southernmost point of the Americas.
