Gretchaninov started his musical studies rather late, because his father, a businessman, had expected the boy to take over the family firm.
Rimsky-Korsakov immediately recognized Gretchaninov's extraordinary musical imagination and talent and gave him much extra time as well as considerable financial help.
Though Gretchaninov remained in Russia for several years after the Revolution, he ultimately chose to emigrate, first to France in 1925, and then, at the age of 75, to the United States in 1939.
He died in New York at the age of 91 and is buried outside the church at Rova Farms, a Russian enclave in Jackson Township, Ocean County, New Jersey.
Gretchaninov wrote five symphonies, the first premiered by Rimsky-Korsakov; four string quartets, the first two of which won important prizes, two piano trios, sonatas for violin, cello, clarinet, piano and balalaika, several operas, song cycle Les Fleurs du Mal, op.
