Barry Kay (1932–1985). Australian theatre designer and photographer.

Barry Kay studied painting at the Académie Julian in Paris and theatre design at the Royal Melbourne Institute of Technology. He worked as an assistant to designer Kenneth Rowell before settling in London in 1956. Kay worked in theatre and opera, as well as extensively in ballet, first with Peter Darrell and Elizabeth West at Western Theatre Ballet, and then with Kenneth MacMillan, for whom he designed Images of Love, Divertimento, The Sleeping Beauty, Cain and Abel, Miss Julie, Anastasia (considered by many to be his greatest work for the theatre, and a milestone in design for ballet in the latter half of the 20th Century), The Four Seasons, Métaboles, Solitaire and Isadora. He was also noted for his designs of classical productions by Marius Petipa as staged by Rudolf Nureyev, including Don Quixote and Raymonda Act III. Kay developed a keen interest in photography, resulting in a portfolio that explored tattooing, body piercing and modification, female bodybuilding, transvestites and transsexuals.
