or Washington, D.C." Likewise, in the analysis of Aaron Kula, director of The Klezmer Company, …the Jewish experience has always been best expressed by music, and Broadway has always been an integral part of the Jewish-American experience… The difference is that one can expand the definition of "Jewish Broadway" to include an interdisciplinary roadway with a wide range of artistic activities packed onto one avenue—theatre, opera, symphony, ballet, publishing companies, choirs, synagogues and more. This vibrant landscape reflects the life, times and creative output of the Jewish-American artist. In the 19th and early 20th centuries the European operetta, a precursor the musical, often featured the work of Jewish composers such as Paul Abraham, Leo Ascher, Edmund Eysler, Leo Fall, Bruno Granichstaedten, Jacques Offenbach, Emmerich Kalman, Sigmund Romberg, Oscar Straus and Rudolf Friml; the latter four eventually moved to the United States and produced their works on the New York stage. One of the librettists for Bizet's Carmen (not an operetta proper but rather a work of the earlier Opéra comique form) was the Jewish Ludovic Halévy, niece of composer Fromental Halévy (Bizet himself was not Jewish but he married the elder Halevy's daughter, many have suspected that he was the descendant of Jewish converts to Christianity, and others have noticed Jewish-sounding intervals in his music). The Viennese librettist Victor Leon summarized the connection of Jewish composers and writers with the form of operetta: "The audience for operetta wants to laugh beneath tears—and that is exactly what Jews have been doing for the last two thousand years since the destruction of Jerusalem". Another factor in the evolution of musical theatre was vaudeville, and during the early 20th century the form was explored and expanded by Jewish comedians and actors such as Jack Benny, Fanny Brice, Eddie Cantor, The Marx Brothers, Anna Held, Al Jolson, Molly Picon, Sophie Tucker and Ed Wynn. During the period when Broadway was monopolized by revues and similar entertainments, Jewish producer Florenz Ziegfeld dominated the theatrical scene with his Follies. By 1910 Jews (the vast majority of them immigrants from Eastern Europe) already composed a quarter of the population of New York City, and almost immediately Jewish artists and intellectuals began to show their influence on the cultural life of that city, and through time, the country as a whole. Likewise, while the modern musical can best be described as a fusion of operetta, earlier American entertainment
