Where is Arcady Yegudkin from? How does he get to America? What is his story?

Yegudkin and his wife are from Russia. When the Bolsheviks kill the Kerenskyites, Yegudkin and his wife are left for dead. He is unharmed; his wife is terribly injured. He and his wife make their way to Europe, where Yegudkin plays with great orchestras. He eventually goes to America, and in New York finds he is too deaf to play for symphony orchestras any longer. He gives French horn lessons at the Eastman School of Music.
