Fumed Oak is a short play in two scenes by Noël Coward, one of ten that make up Tonight at 8:30, a cycle written to be performed across three evenings. Coward billed the work as an "unpleasant comedy in two scenes". The play concerns a downtrodden, middle-aged salesman who, having saved up enough money to cut all ties, walks out on his wife, mother-in-law and "horrible adenoidal daughter", having first told all three what he thinks of them.
In the introduction to a published edition of the plays, Coward wrote, "A short play, having a great advantage over a long one in that it can sustain a mood without technical creaking or over padding, deserves a better fate, and if, by careful writing, acting and producing I can do a little towards reinstating it in its rightful pride, I shall have achieved one of my more sentimental ambitions."
The play was first produced in 1935 in Manchester and on tour and played in London (1936), New York (1936–1937) and Canada (1938). It has enjoyed several major revivals and has been adapted for film. At its premières in Manchester and London Fumed Oak was played on the same evening as Hands Across the Sea and Shadow Play. Like all the other plays in the cycle it originally starred Gertrude Lawrence and Coward himself.
Coward later said, "I have always had a reputation for high-life, earned no doubt in the twenties with such plays as The Vortex. But, as you see, I was a suburban boy, born and bred in the suburbs of London, which I've always loved and always will." Fumed Oak, like his later play This Happy Breed, is one of his rare stage depictions of suburban life.
Six of the plays in Tonight at 8:30 were first presented at the Opera House, Manchester, beginning on 15 October 1935.Fumed Oak premiered on the third night, 18 October 1935. A seventh play was added on the subsequent provincial tour, and the final three were added for the London run. The first London performance was on 18 January 1936 at the Phoenix Theatre.
Coward directed all ten pieces, and each starred Coward and Gertrude Lawrence. Coward said that he wrote them as "acting, singing, and dancing vehicles for Gertrude Lawrence and myself". The plays were performed in various combinations of three at each performance during the original run. The plays chosen for each performance were announced in advance, although a myth evolved that the groupings were random. Matinées were sometimes billed as Today at 2:30. The title of the play refers to a wood finishing process that treats the oak with ammonia fumes to darken it and emphasise its rough grain; the finish is dull rather than glossy.
