Geoffrey David Marsh (born 16 August 1957, in Nottingham, Great Britain) is an English museum professional who runs the Theatre and Performing Arts department of the Victoria and Albert Museum. He started his career at the Museum of London and was Project Director for the Imperial War Museum North in Manchester from 1993 to 1999. Bowie had saved most of the artifacts, costumes, and props from his career and had almost 75,000 pieces in a private collection. Bowie allowed Victoria Broackes and Geoffrey Marsh, the V&A museum curators, free access to his archives for the show, although he did not get involved with how the pieces were displayed, nor the narrative of the show itself.
