George Harrison Marks (6 August 1926 – 27 June 1997) was an English glamour photographer and director of nudist films. In the 1950s Marks and pin-up model, Pamela Green, opened a photographic studio and they launched Kamera magazine in 1957. Kamera featured Marks' glamour photography of nude women taken in the small studios or Marks' kitchen. Marks' 1958 publicity materials contained one of the first uses of the word "glamour" as a euphemism for nude modelling/photography. The magazine was an immediate success and the business expanded to employ around seventeen staff by the early 1960s, selling a number of other magazine titles such as Solo, postcards and calendars, and distributing imported French books and glamour magazines.
