LOS ANGELES — Alexander “Sandy” Courage, an Emmy-winning and Academy Award-nominated arranger, orchestrator and composer who created the otherworldly theme for the classic “Star Trek” TV show, has died. He was 88.

Courage died May 15 at the Sunrise assisted-living facility in Pacific Palisades, his stepdaughter, Renata Pompelli of Los Angeles, said Thursday. He had been in poor health.

Over a decades-long career, Courage collaborated on dozens of movies and orchestrated some of the greatest musicals of the 1950s and 1960s, including “My Fair Lady,” “Hello, Dolly!,” “Gigi,” “Porgy and Bess” and “Fiddler on the Roof.”

But his most famous work is undoubtedly the “Star Trek” theme, which he composed, arranged and conducted in a week in 1965.

“I have to confess to the world that I am not a science fiction fan,” Courage said in an interview for the Academy of Television Arts &Sciences Foundation’s Archive of American Television in 2000. “Never have been. I think it’s just marvelous malarkey. … So you write some, you hope, marvelous malarkey music that goes with it.”
