Stephen Sondheim

American composer and lyricist. Regarded as one of the most important figures in 20th-century musical theater, he is credited for reinventing the American musical. With his frequent collaborations with Hal Prince and James Lapine, Sondheim's Broadway musicals tackled unexpected themes that ranged beyond the genre's traditional subjects, while addressing darker elements of the human experience. His music and lyrics were tinged with complexity, sophistication, and ambivalence about various aspects of life.
