Born in New York in 1944 to an Austrian-immigrant father who played accordion, Marvin Hamlisch displayed prodigious musical talent from early childhood, mimicking piano music by ear at age five and gaining admission to the Juilliard School Pre-College Division at six. By his mid-teens, he was working as a rehearsal pianist for *The Bell Telephone Hour* and assisting on the original Broadway production of *Funny Girl*; his first commercial hit, "Sunshine, Lollipops and Rainbows" (co-written with Howard Liebling and recorded by Lesley Gore), reached the Billboard Hot 100 at age 21 in 1965. Over the following decades, Hamlisch became one of the most prolific and decorated composers in American entertainment, seamlessly moving between Broadway stages and Hollywood soundstages with equal mastery. His 1975 musical *A Chorus Line*—for which he won both the Tony Award for Best Original Score and the Pulitzer Prize for Drama—remains a landmark work in American musical theatre, while his film scores for *The Way We Were* (1973) and *The Sting* (1973) earned him three Academy Awards in a single night in 1974, a feat matched by few composers in cinema history. Hamlisch's gift lay not merely in melody but in his ability to distill emotional complexity into immediately accessible music, whether composing original scores or, as in *The Sting*, arranging Scott Joplin's ragtime compositions with such sophistication that they became central to the film's artistic identity. He continued composing for stage and screen until his death in Los Angeles in 2012, leaving behind a catalogue that defined the sound of American popular entertainment for nearly five decades.
