Stuart Parr is a designer of sumptuously simple buildings and interiors. He’s a gallerist with a focus on high modern furnishings. He’s a producer of movies including 2002’s Oscar-winning 8 Mile and 2005’s Get Rich or Die Tryin’. He is the manager of knighted Australian industrial designer Marc Newson, and a curator of exhibitions of decorative arts. To call Parr a polymath would do the man a terrible injustice.
