Sloane, A[lfred] Baldwin (1872–1925), composer. The most prolific songwriter for musical comedies at the turn of the century, he wrote the scores for no fewer than two dozen Broadway musicals between 1896 and 1912. He was born in Baltimore, where his songs were first heard in amateur productions. Coming to New York he began interpolating melodies into others' scores and soon was invited to create his own. His biggest hit was “Heaven Will Protect the Working Girl,” which Marie Dressler introduced in Tillie's Nightmare (1910), but none of his songs found enduring popularity. Among Sloane's shows were The Mocking Bird (1902), The Wizard of Oz (1903), Lady Teazle (1904), and The Summer Widowers (1910). He composed only rarely after 1912, but he did provide much of the music for the 1919 and 1920 Greenwich Village Follies. His last score, for China Rose (1925), was heard after his death.
Sloane, A. Baldwin [Alfred Baldwin Sloane] (1872–1925), American theatre composer. The most prolific Broadway composer at the turn of the century, Sloane scored some two dozen New York musicals between 1896 and 1912. Born in Baltimore, where his songs were first heard in such semi‐professional theatres as his own Paint and Powder Club, he arrived in New York in 1894 and soon had his melodies interpolated into others' scores, such as the successful Excelsior, Jr. (1895). His first full score in New York was for the children's extravaganza Kinder‐ und Hausmärchen (1896), which featured such familiar characters as King Cole, Miss Muffett, Old Mother Hubbard, Sindbad the Sailor, and Puss‐in‐Boots. Sloane's most famous Broadway musical was The Wizard of Oz (1903), in which he collaborated with the author L. Frank Baum. Because they were played by popular stars, Dave Montgomery and Fred Stone, the characters of the Scarecrow and the Tin Man dominated the show. Other Sloane musicals that contained fairy‐tale or fantasy elements include The Hall of Fame (1902), The Gingerbread Man (1905), and Tillie's Nightmare (1910), which featured his most famous song, ‘Heaven Will Protect the Working Girl’. Sloane was not a distinguished composer and few of his songs became popular, but he was a competent craftsman with a sound theatrical sense.
