Germaine Yvonne Arnaud was a French-born pianist, singer and actress, who was well known for her career in Britain, as well as her native land. After beginning a career as a concert pianist as a child, Arnaud acted in musical comedies. She switched to non-musical comedy and drama around 1920 and was one of the players in the second of the Aldwych farces, A Cuckoo in the Nest, a hit in 1925. She also had dramatic roles and made films in the 1930s and 1940s, and continued to act into the 1950s. She occasionally performed as a pianist later in her career. The Yvonne Arnaud Theatre was named in her memory in Guildford, Surrey.

The Aldwych farces were a series of twelve stage farces presented at the Aldwych Theatre, London, nearly continuously from 1923 to 1933. All but three of them were written by Ben Travers. They incorporate and develop British low comedy styles, combined with clever word-play. The plays were presented by the actor-manager Tom Walls and starred Walls and Ralph Lynn, supported by a regular company that included Robertson Hare, Mary Brough, Winifred Shotter, Ethel Coleridge, and Gordon James.
