Book excerpt: Arthur Schwartz (1900-1984), a premier composer of American Popular Song during the mid-20th century, has been overlooked by historians. This first full-length biography covers his work on Broadway and in Hollywood, where he was known as the "master of the intimate revue" for his songs in the 1930s with Howard Dietz. Schwartz wrote music for films in the 1940s--with Academy Award nominations for They're Either Too Young or Too Old and A Gal in Calico--produced two popular movie musicals--Cover Girl and Night and Day--and was among the first songwriters to work in the new medium of television. The author describes his creative process and includes behind-the-scenes stories of each of his major musicals.
