12701 Chénier           Discovered 1990 Apr. 15 by E. W. Elst at the European Southern Observatory.
André Chénier (1762-1794) was a French poet who died on the scaffold. The son of a Greek mother and an atheist father, he was inspired by Lucretius' De rerum natura, Holbach's Système de la Nature and d´Alembert's Rêve to write his naturalistic poem Hermès.
