[2][3] Prior to the outbreak of World War I he taught at the Stern Conservatory in Berlin, but in 1914 he settled in New York City, where he made his US debut.
Two other students who went on to important pianistic careers were the American Abram Chasins, and the Australian Bruce Hungerford.
He also taught Muriel Kerr, a winner of the Naumberg Competition who made her Carnegie Hall debut 5 December 1928 in Rachmaninoff's Concerto No.
She became Hutcheson's assistant at Juilliard and later toured under Columbia Artists Management, settling finally in Los Angeles where she taught at the University of Southern California.
Further, he had never scored a large symphonic work (the earlier Rhapsody in Blue had been scored for jazz band by Gershwin, but was orchestrated by Ferde Grofé) and was under great stress from the pressing deadline expectations from Walter Damrosch, conductor of the New York Symphony, who had commissioned the Concerto in F. Thanks to Ernest Hutcheson's kind offer of seclusion for Gershwin at Chautauqua where his quarters were declared off limits to everyone until 4 p.m. daily, Gershwin was able to successfully complete his piano concerto on time.
