After the war they were at last free to leave Germany, and in 1919 emigrated to New York City in the United States. Lhévinne continued his concert career and also taught piano at the Juilliard School. Regarded as one of the supreme technicians of his day by virtually all of his more famous contemporaries (even Vladimir Horowitz admired his pianistic command), he never achieved their level of success with the public. He may have made his excellence look and sound too easy, but he also enjoyed teaching more than performing. He settled into a life of concert tours and teaching. Lhévinne spent time each summer starting in 1922, at Bonnie Oaks, relaxing from public life and sometimes teaching young musicians. He died suddenly from a heart attack in 1944 a few days short of his 70th birthday.
