Boris Hambourg was the third son of Michael Hambourg , and the younger brother of the pianist Mark Hambourg (1879--1960) and the violinist Jan Hambourg (1882--1947). The three sons were encouraged in music from an early age, and were taught instruments which enabled them to play together in chamber music ensemble, as the Hambourg Trio. Boris began his studies in London in 1892, and after devoting some time to piano, decided to specialize in the cello. He studied at the Hoch Conservatory in Frankfort-am-Main from 1898 to 1903, taking lessons from Herbert Walenn and later from Hugo Becker.
