Tristram Ogilvie Cary (1925–2008) was a British composer, musicologist, and educator, known for his significant contributions to contemporary classical music and electronic music. Cary's genre-spanning work encompassed orchestral, chamber, and electronic compositions, often integrating innovative techniques and sound exploration. One of his notable achievements includes the composition of the score for the 1960 Doctor Who serial "The Daleks," marking one of the earliest uses of electronic music in television. Cary's pioneering approach to sound synthesis and composition laid groundwork for future electronic music practices. He created a range of works, including "Concerto for Piano and Orchestra" and "A Symphony of Poems," which showcased his ability to blend traditional and modern musical elements. Cary's impact extended beyond composition; he was also instrumental in music education, serving as a faculty member at various institutions, including the University of Adelaide, where he helped cultivate a new generation of composers. His contributions to both the sonic landscape of film and television and academic discourse in music solidified his legacy as a vital figure in 20th-century music.
