Mark Trent Goldberg, exec director of the Ira and Leonore Gershwin Trust, died of a heart attack May 18 in his San Francisco office. He was 49.

He managed the Gershwin Archive, working closely with the Library of Congress, and in 1999, restored material for the City Center Encores production of “The Ziegfeld Follies of 1936.”

Gershwin music was his business and his pleasure. For 25 years he tended to the music professionally and personally. He began his career as a musical actor in his hometown of San Jose, Calif., and continued as a theater student at UCLA, where he earned a teaching credential specializing in early childhood education.

He performed in Los Angeles productions including “Leave It to Jane” and “The Boys From Syracuse” (both at the then-Doolittle Theater), “Annie” (with John Schuck), “Cradle Will Rock” (with George Gaynes), “Starship Shakespeare” (Odyssey Theater), “Partners” (Matrix Theater) and “Seymour Glick” (written and directed by Steve Allen), before beginning his work with Leonore Gershwin.

He is survived by his parents and two sisters.
