Bloch was born in Geneva on July 24, 1880 to Jewish parents. He began playing the violin at age 9. He began composing soon after. He studied music at the conservatory in Brussels, where his teachers included the celebrated Belgian Violinist Eugène Ysaÿe. He then travelled around Europe, moving to Germany (where he studied composition from 1900–1901 with Iwan Knorr at the Hoch Conservatory in Frankfurt), on to Paris in 1903 and back to Geneva before settling in the United States in 1916, taking US citizenship in 1924. He held several teaching appointments in the USA with George Antheil, Frederick Jacobi, Quincy Porter, Bernard Rogers, and Roger Sessions among his pupils.
