Boleslav Leopoldovich Yavorsky was a Russian musicologist, music teacher, administrator and pianist. Through his teachings and editorial positions he heavily influenced Soviet music theory. However, outside Soviet circles, he has had little impact. He studied at the Moscow Conservatory under Sergei Taneyev. He taught at the Kiev Conservatory until 1919, the First Music Tekhnikum in Moscow, which he founded, and the Moscow Conservatory. He chaired the music section of Narkompros from 1922 to 1930. Yavorsky was a friend, mentor and confidant of the composer Dmitri Shostakovich and played an important role in the latter's development. He often used his influence to further Shostakovich's career. His students included Vladimir Aleksandrovich Dukelsky (also known as Vernon Duke), Alexei Fedorovich Kozlovsky, Alexander Abramovich Krein, Sergei Protopopovand Mykola Leontovych.
