Nikolai Rubinstein
Unfulfilled with civil service, and persuaded by Dubuque, he returned to Moscow in 1867 to become a private teacher. In 1870, Nikolai Rubinstein asked him to teach at the Moscow Conservatory, which he did. At one point, he also studied harmony with Tchaikovsky. Zverev never married. He died at the age of 60, in 1893.
