World War I, with the birth of jazz, ragtime and new dance styles like the foxtrot and tango, Herbert reluctantly switched to writing musical comedies. These featured less elaborate ensembles and simpler songs for less classically trained singers than the European-style operettas that had dominated his earlier career. Herbert, during the last years of his career, was frequently asked to compose ballet music for the elaborate production numbers in Broadway revues and the shows of Irving Berlin and Jerome Kern, among others. He was also a contributor to the Ziegfeld Follies every year from 1917 to 1924. Death and legacy A healthy man throughout his life, Herbert died suddenly of a heart attack at the age of 65 on May 26, 1924, shortly after his final show, The Dream Girl, began its pre-Broadway run in New Haven, Connecticut. He was survived by his wife and two children, Ella Victoria Herbert Bartlett and Clifford Victor Herbert. He was entombed in Woodlawn Cemetery in The Bronx, New York City. Herbert and his music are celebrated in the 1939 film The Great Victor Herbert, where he was portrayed by Walter Connolly and which also featured Mary Martin. He was also portrayed by Paul Maxey in the 1946 film Till the Clouds Roll By. Many of Herbert's own works were made into films, and his music has been used in numerous films and television shows. In 1940 the U.S. Postal Service included Herbert in its Famous Americans series of stamps. A Chicago elementary school is named for him. During World War II the Liberty ship was built in Panama City, Florida, and named in his honor. Ireland's RTÉ Lyric FM's feature "Victor Herbert, Son of Dublin" was Silver Radio Winner at the 2019 New York Festivals International Radio Awards in the category best biographical documentary.
