Olivia Madeline Grace Mary Wyndham was a British society photographer and a member of the 1920s socialite group known as the bright young things.

The Bright Young Things, or Bright Young People, was a term given by the tabloid press to a group of Bohemian young aristocrats and socialites in 1920s London. They threw flamboyant fancy dress parties, went on elaborate treasure hunts through nighttime London, and some drank heavily or used illicit drugs — all of which was enthusiastically covered by journalists such as Charles Graves and Tom Driberg.
