13770 Commerson           Discovered 1998 Sept. 20 by E. W. Elst at the European Southern Observatory.
Philibert Commerson (1727-1773) was a French naturalist, botanist and explorer. In 1764 he joined Bougainville on the frigate Boudeuse to circumnavigate the world. Near Rio de Janeiro he found a vivid colorful vine, which upon his suggestion was named Bougainvillea by the French botanist de Jussieu.
