Harry Breuer was born in Brooklyn, New York on October 24, 1901. He began his musical study with the violin but, at age thirteen, the xylophone caught his interest and he made his musical debut as soloist at the New York Academy of Music in 1919. The twenties found him as a pioneer radio broadcaster and soloist at the Roxy Theatre and other movie palaces. When Radio City Music Hall opened in the thirties he performed as soloist using an instrument of his own design—a combination of marimba, vibraphone and xylophone.
His career in music was multi-faceted as a composer of mallet solos, appearances in film shorts and educational films, soloist on recordings, staff percussionist at NBC and composer and performer of electronic music for European radio, television and films.
