Victor August Herbert (February 1, 1859 - May 26, 1924) was an Irish-born, German-raised American composer, cellist and conductor. Although Herbert enjoyed important careers as a cello soloist and conductor, he is best known for composing many successful operettas that premiered on Broadway from the 1890s to World War I. He was also prominent among the tin pan alley composers and was later a founder of the American Society of Composers, Authors, and Publishers (ASCAP). A prolific composer, Herbert produced two operas, a cantata, 43 operettas, incidental music to 10 plays, 31 compositions for orchestra, nine band compositions, nine cello compositions, five violin compositions with piano or orchestra, 22 piano compositions and numerous songs, choral compositions and orchestrations of works by other composers, among other music.

On December 1, 1888, Seidl programmed Herbert's Serenade for String Orchestra, Op. 12 as part of a concert at Steinway Hall, with the composer conducting. In January, Herbert and violinist Max Bendix were the soloists in the American premiere of the challenging Double Concerto, Op. 102 for Violin, Cello and Orchestra by Brahms. Conductor Theodore Thomas then invited Herbert to conduct and perform with him in Chicago. In 1889, Herbert formed the Metropolitan Trio Club with Bendix and pianist Reinhold L. Herman. The Musical Courier gave effusive praise to both Herbert's compositions ("refined taste, abundant melodic invention") and his playing: "As a violoncellist, Mr. Herbert ranks with the foremost alive". Seidl brought Herbert, Forster, Bendix, Juchs, Ohe and Lilli Lehmann, together with a large orchestra and 500-voice chorus, to Pittsburgh, Pennsylvania in May 1889 as part of a big music festival to celebrate the new Exposition Building. Herbert also played and conducted for the Worcester Music Festival, where he returned repeatedly through the 1890s. In the autumn of 1889, Herbert also joined the faculty of the National Conservatory of Music, where he taught cello and music composition for several years. In 1890, he was appointed the conductor of the Boston Festival Orchestra, serving there in seasons through 1893, in addition to all of his conducting commitments elsewhere. In 1891, Herbert premiered an ambitious cantata, The Captive, for solo voices, chorus and full orchestra. His Irish Rhapsody (1892) enjoyed a brief but intense period of popularity. He became director of the 22nd Regimental Band of the New York National Guard in 1894, succeeding its founder, Patrick Gilmore and Gilmore's unsuccessful immediate successor David Wallis Reeves. Herbert toured widely with the 22nd Regimental Band through 1900, performing both his own band compositions and works from the orchestral repertory that he transcribed for the band. Beginning in 1894, when he began composing operettas, Herbert's band marches were sometimes derived from material from the operettas. Throughout his career, Herbert was well liked by orchestra players for his modesty and unpretentiousness. Herbert continued to compose orchestral music, writing one of his finest works, the Cello Concerto No. 2 in E minor, Op. 30, which premiered in 1894. In 1898, Herbert became the principal conductor of the Pittsburgh Symphony, a position he held until 1904. Under his leadership, the orchestra became a major American ensemble and was favorably compared by music critics with ensembles like the New York Philharmonic and Boston Symphony Orchestra. The orchestra toured to several major cities during Herbert's years as conductor, notably premiering Herbert's Auditorium Festival March for the celebration of the twelfth anniversary of Chicago's Auditorium Theatre in 1901. After a disagreement with the management of the Pittsburgh Symphony in 1904, Herbert resigned, founding the Victor Herbert Orchestra. He conducted their programs of light orchestral music paired with more serious repertoire (as he had done earlier with Anton Seidl's Brighton Beach orchestra concerts) at summer resorts and on tours for most of his remaining years. His orchestra made many acoustical recordings for both Edison Records, from 1909 to 1911, and the Victor Talking Machine Company, from 1911 to 1923. Herbert was also a cello soloist in several Victor recordings as well.
