8557 Saroun           Discovered 1995 July 23 by L. Sarounova at Ondrejov.
Named in honor of the discoverer's father, Jaroslav Saroun (b. 1943). A teacher at the Prague Academy of Musical Arts and a member of the Czech Philharmonic Orchestra, he is a pianist who is always in great demand as an accompanist for Czech and foreign singers. As a lover of astronomy, he influenced and supported his daughter in her desire to become an astronomer. This minor planet was discovered on the day after his birthday.
