American composer and arranger (1923–2008) who wrote the theme and background music of Star Trek: The Animated Series, credited under the pseudonym Yvette Blais.
Ray Ellis was an American composer, arranger and conductor, born in 1923. As an arranger he worked with many singers, most famously on Billie Holiday's album Lady in Satin.
From the late 1960s he supplied music for the animation studio Filmation, and in 1973 he composed the theme and the library of cues used throughout Star Trek: The Animated Series. On screen the music is credited to Yvette Blais and Jeff Michael, pseudonyms for Ellis and Filmation producer Norm Prescott.
Because the original series theme was not used, Ellis wrote a new fanfare-led title tune in a similar spirit, and his small set of action and mystery cues was reused across all twenty-two episodes. He died in 2008.
