Frederick Jacobi (May 4, 1891 – October 24, 1952) was an American composer and teacher. His works include symphonies, concerti, chamber music, works for solo piano and for solo organ, lieder, and one opera.
He taught at Juilliard School of Music and served as the director of the American section of the International Society for Contemporary Music. He was also a founding member of the League of Composers. His notable students included Mark Bucci and John Verrall. He died on October 24, 1952 in New York City of heart failure.
Frederick Jacobi was the son of San Francisco wholesale wine merchant, Frederick Jacobi Sr. and Flora Brandenstein, whom Frederick Sr. had married in 1876. During the composer's childhood years, he demonstrated his musical talent, composing short pieces at the piano and playing tunes from contemporary musical comedies by ear. In these years the family traveled each summer to visit relatives in New York City. The scenery of those cross-country train rides later provided the themes of a number of Jacobi's nature-inspired compositions.
When Frederick Sr. died in 1911, Frederick Jr. inherited the estate, which provided him enough wealth that he could devote his entire livelihood to music. In his twenties Jacobi studied music and composition under such masters as Isidore Philippe of the Paris Conservatory, Rafael Joseffy, Paolo Gallico, Ernest Bloch and Rubin Goldmark in New York, and Paul Juon in Berlin.
From 1913 to 1917 he worked as a vocal coach and assistant conductor at the Metropolitan Opera. It was during that time, on April 19, 1917, that he married Irene Schwarcz, a friend of many years, who, at the time, was studying piano at the New York Institute of Musical Art (which later became Juilliard). Irene would go on to become an accomplished concert pianist and would play piano parts in many performances and recordings of Jacobi's works.
