4109 Anokhin           Discovered 1969 July 17 by B. A. Burnasheva at the Crimean Astrophysical Observatory.
Named in memory of Sergej Nikolaevich Anokhin (1910-1986), test pilot and sportsman. During one of his test flights he lost an eye, but he later reverted to test work. During the last years of his life he was a trainer of the Soviet cosmonauts.
