Sir Gerald Hubert Edward Busson du Maurier was an English actor and manager. He was the son of author George du Maurier and his wife, Emma Wightwick, and the brother of Sylvia Llewelyn Davies. In 1903, he married the actress Muriel Beaumont, with whom he had three daughters: writers Angela du Maurier (1904–2002) and Dame Daphne du Maurier (1907–1989), and painter Jeanne du Maurier (1911–1997). His popularity was due to his subtle and naturalistic acting: a "delicately realistic style of acting that sought to suggest rather than to state the deeper emotions". His Times obituary said of his career: "His parentage assured him of engagements in the best of company to begin with; but it was his own talent that took advantage of them."

George Louis Palmella Busson du Maurier was a Franco-British cartoonist and writer known for work in Punch and a Gothic novel Trilby, featuring the character Svengali. His son was the actor Sir Gerald du Maurier. The writers Angela du Maurier and Daphne du Maurier and the artist Jeanne du Maurier were all granddaughters of George. He was also father of Sylvia Llewelyn Davies and grandfather of the five boys who inspired J. M. Barrie's Peter Pan.
