Dr. Samuel J. Hoffman (born July 23, 1903 in Manhattan; died December 6, 1967) was a notable thereminist who played with Les Baxter and played theremin on several film soundtracks. He was also an adviser on soundtracks, such as the ones for Spellbound (1945) and The Day the Earth Stood Still (1951), as he was the only thereminist in the Los Angeles Musician's Union. Like many early thereminist he started as a violinist. He was referred to as "Doctor" because he was also a podiatrist.
