When her teacher became ill, a family friend suggested that she continue her studies with Josef Lhévinne, a talented student at the Moscow Imperial Conservatory, five years older than Rosina.
[3][4] Together they lived and taught in Moscow, Tbilisi, Georgia and later in Berlin before emigrating after World War I and the Russian Revolution to New York, where they joined the faculty of the Institute of Musical Art which later became The Juilliard School.
At the height of the Cold War in 1958, he was awarded the First Prize at the inaugural Tchaikovsky Competition in Moscow, becoming an instant worldwide celebrity and bringing international fame to his teacher.
Other Lhévinne students include Martin Canin (her teaching assistant), James Levine (music director of the Metropolitan Opera), John Williams (composer and conductor of the Boston Pops Orchestra), the composer Judith Lang Zaimont, pianists John Browning, Walter Buczynski, Kun Woo Paik, Seth Carlin, Eduardo Delgado, Madeleine Forte, Edna Golandsky, Tong-Il Han, Anthony & Joseph Paratore, Daniel Pollack, Marcus Raskin, Misha Dichter, Edward Auer, Santos Ojeda, Joel Ryce-Menuhin, Garrick Ohlsson, Joseph William Fennimore, Hiroko Nakamura, Selma Epstein, Robelyn Schrade, Neal Larrabee, Jeffrey Biegel and many others including several present-day teachers at the Juilliard School.
Lhévinne reconsidered her decision never to play in public as a soloist, and in her 70s and 80s she made a remarkable series of appearances, first in collaboration with the Juilliard String Quartet, and later in concertos at the Aspen Summer Music Festival.
