Diran Alexanian
Diran Alexanian was an Armenian cello teacher. He studied cello with Friedrich Grützmacher in Leipzig, as well as played chamber music with Johannes Brahms and violinist Joseph Joachim. At a young age he was an accomplished cellist, performing at age seventeen the solo part of Richard Strauss's Don Quixote.
At age twenty, Alexanian settled in Paris, where he met Pablo Casals. Casals had seen Alexanian perform, and noticed that Alexanian's fingering was in line with his new way of playing the cello. They got to know one another, finding they had similar views on general and interpretation of music.
In 1921, Alexanian became the assistant to Casals at the École Normale de Musique for Cello and Orchestra, under conductor Alfred Cortot.
Alexanian abandoned his position at the École in 1937, and moved to the United States. There he taught both at the Peabody Institute in Baltimore, and the Manhattan School of Music in New York City. There his students included Bernard Greenhouse, David Soyer, George Ricci, Raya Garbousova, David Wells, and Mischa Schneider.
