Alan Jay Lerner (August 31, 1918 – June 14, 1986) was a prominent American lyricist and librettist known for his significant contributions to musical theater. Born in New York City into a prosperous Jewish family, Lerner was the son of Edith and Joseph Jay Lerner, cofounder of Lerner Stores, a chain of women's clothing shops. He was educated at prestigious institutions, including Bedales School in England, Choate School in Connecticut, Juilliard, and Harvard University, where he contributed to the Hasty Pudding Theatricals.

Lerner's career in musical theater began in earnest when he met composer Frederick Loewe at The Lambs Club in New York City in 1942. Together, they created some of the most enduring works of musical theater, including "Brigadoon" (1947), "My Fair Lady" (1956), and "Camelot" (1960). Their collaboration extended to film, with "Gigi" (1958) winning nine Academy Awards. Lerner also worked with other composers, such as Kurt Weill and Burton Lane, and won an Academy Award for the screenplay of "An American in Paris" (1951).

Despite personal challenges, including multiple marriages and health issues, Lerner's influence on American musical theater remains profound. He won numerous awards, including three Tony Awards and three Academy Awards, and his works continue to resonate with audiences worldwide. Lerner passed away in New York City in 1986 from lung cancer, leaving behind a legacy of lyrical beauty and emotional depth in musical theater.
