Alfred Grünwald (1884-1951) was an Austrian author, librettist, and lyricist. Some of his better-known works were written in conjunction with the composers Franz Lehár, Emmerich Kalman, Oscar Straus, Paul Abraham, and Robert Stolz. Alfred Grünwald worked for a theatrical agency before turning to libretto writing. A number of Grünwald's librettos were produced on Broadway. These included COUNTESS MARITZA (1926), THE YANKEE PRINCESS (1922), THE CIRCUS PRINCESS (1927), and THE DUCHESS OF CHICAGO (1929). He also wrote a number of comedies, including CANCING PARTNER (1930), written in collaboration with Alexander Engel and produced on Broadway by David Belasco. Besides writing over 40 operetta librettos, Alfred Grünwald also wrote non-musical plays, short stories, and newspaper articles, and was the theater critic for the Neue Wiener Journal. He was a member of the American Society of Composers, Authors and Publishers.
