Samuel L. M. Barlow
 Samuel L. M. Barlow (June 1 1892 - September 19 1982) was a Harvard-educated American composer pianist and art critic. His compositional style was conservative for his day and he once stated that he wrote tunes that wouldn't shock Papa Brahms. However his music was innovative in its frequent exploration of new performance techniques and practices; including the use of slide projections for his 1936 symphonic concerto Babar.
