Frederick Loewe grew up in Berlin and attended a Prussian cadet school from the age of five until he was thirteen. At an early age Loewe learned to play piano by ear and helped his father rehearse, and he began composing songs at age seven. He eventually attended a music conservatory in Berlin, one year behind virtuoso Claudio Arrau, and studied with Ferruccio Busoni and Eugene d'Albert. He won the coveted Hollander Medal awarded by the school and gave performances as a concert pianist while still in Germany. At 13, he was the youngest piano soloist ever to appear with the Berlin Philharmonic.
In 1924, his father received an offer to appear in New York City, and Loewe traveled there with him, determined to write for Broadway. This proved to be difficult, and he took other odd jobs, including cattle punching, gold mining and prize fighting. He eventually found work playing piano in German clubs in Yorkville and in movie theaters as the accompanist for silent films.
Loewe began to visit the Lambs Club, a hangout for theater performers, producers, managers, and directors. There, he met Alan Jay Lerner in 1942. Their first collaboration was a musical adaptation of Barry Connor's farce The Patsy, called Life of the Party, for a Detroitstock company. It enjoyed a nine-week run and encouraged the duo to join forces with Arthur Pierson for What's Up?, which opened on Broadway in 1943. It ran for 63 performances and was followed two years later by The Day Before Spring.
Their next Broadway production was Camelot. The production starred Richard Burton, Julie Andrews and Robert Goulet.The trio appeared on The Ed Sullivan Show and sang a few numbers from the musical, along with an appearance by Lerner and Loewe. The following morning the box office was swamped with requests, and Camelot became another hit.
Loewe then decided to retire to Palm Springs, California, not writing anything until he was approached by Lerner to augment the Gigi film score with additional tunes for a 1973 stage adaptation, which won him his second Tony, this time for Best Original Score. The following year they collaborated on a musical film version of The Little Prince, based on the classic children's tale by Antoine de Saint-Exupéry. This film was a critical and box office failure, but the soundtrack recording and the film itself are back in print on CD and DVD.
