Hay Fever is a comic play written by Noël Coward in 1924. Its first production was in the West End in 1925 with Marie Tempest as Judith Bliss. A cross between high farce and a comedy of manners, the play is set in an English country house in the 1920s, and deals with the four eccentric members of the Bliss family and their outlandish behaviour when they each invite a guest to spend the weekend. The self-centred behaviour of the hosts finally drives their guests to flee while the Blisses are so engaged in a family row that they do not notice their guests' furtive departure.
The play's original production opened in London in 1925 and ran for 337 performances. Coward wrote the piece with Tempest in mind for the central role of Judith. In later productions the part has been played by actresses including Constance Collier, Edith Evans, Constance Cummings, Rosemary Harris, Judi Dench, Geraldine McEwan and Felicity Kendal. Hay Fever has been continually revived in Britain, the US and elsewhere, and has been adapted frequently for radio and television.
