Sigmund Romberg was one of Broadway's most prolific composers of operettas and musical theatre, composing music for dozens of theatrical productions. Born in Austria-Hungary in 1887, he initially trained as an engineer in Vienna before turning to music. His major operettas include The Desert Song (1926) and The New Moon (1928), both created with lyricist Oscar Hammerstein II. From these works came enduring standards that entered the jazz repertoire, including "Softly, As in a Morning Sunrise" and "Lover, Come Back to Me" from The New Moon. His later song "When I Grow Too Old to Dream" also became a beloved standard. Working primarily with the Shubert brothers, Romberg bridged European operetta traditions with American musical theatre. He died in New York in 1951.
