Asaf Mikhailovich Messerer (19 November 1903 – 7 March 1992) was a Soviet ballet dancer, teacher and choreographer. He was born in Vilnius, Lithuania. In 1919 he studied privately with Mikhail Mordkin, until Alexander Gorsky placed him in a class at the Bolshoi Ballet School, from which he graduated in 1921. He then joined the Bolshoi Theatre, where he became one of its most important principal soloists, a position he retired from in 1954. Today Messerer is best remembered as a choreographer and an instructor; he was both the choreographer and ballet master for the Bolshoi Theatre. His book Classes in Classical Ballet is a thorough study of proper ballet technique and is still used today. Messerer was the brother of Sulamith Messerer and Rachel Messerer and the uncle of Maya Plisetskaya, Alexander Plisetski and Azari Plisetski, as well as of Mikhail Messerer. He was married to silent film star, Anel Sudakevich. They had one son, Boris Messerer. He won multiple awards from the USSR and Lithuania.
