Robert Heller, also Joseph Heller, (born William Henry Palmer; 1826–1878) was an English magician, mentalist, and musician. The year of his birth is the subject of some speculation; some sources list it as 1829 while others claim 1830.
As the son of a famous concert pianist, Heller began his life as a musician studying at the Royal Academy of Music. After becoming fascinated with magic at age 14, Heller began copying his idol Jean Eugène Robert-Houdin, from whom he adopted his first name. Heller left his scholarship at the academy to become a professional magician.
