Randall Gabrielan's long career in Monmouth County history has produced numerous books, videos, lectures, articles, museum exhibitions and property reports, giving special focus to historical sites. He served as president of the Middletown Township Historical Society for thirty years. During his thirteen and a half years as the executive director of the Monmouth County Historical Commission, he organized the popular annual self-guided tour of sites called A Weekend in Old Monmouth. Gabrielan, who now serves the commission as its vice chair, is often seen in his favorite habitat: the Metropolitan Opera, relaxing during intermission.
