Fortescue-Brickdale was born at her parents' house, Birchamp Villa in Upper Norwood, Surrey as Mary Eleanor Fortescue Brickdale the daughter of Matthew and Sarah Fortescue Brickdale, her father was a barrister. She was trained first at the Crystal Palace School of Art, under Herbert Bone and entered the Royal Academy in 1896. Her first major painting was The Pale Complexion of True Love (1899). She soon began exhibiting her oil paintings at the Royal Academy, and her watercolours at the Dowdeswell Gallery, where she had several solo exhibitions.
While at the academy, she came under the influence of John Byam Liston Shaw, a protégé of John Everett Millais much influenced by John William Waterhouse. When Byam Shaw founded an art school in 1911, Fortescue-Brickdale became a teacher there.
In 1909, Ernest Brown, of the Leicester Galleries, commissioned a series of 28 watercolour illustrations to Tennyson's Idylls of the King, which she painted over two years. They were exhibited in the gallery in 1911, and 24 of them were published the next year in a deluxe edition of the first four Idylls 
Later, she also worked with stained glass. She was a staunch Christian, and donated works to churches. Amongst her best known works are The Uninvited Guest and Guinevere. She died on 10 March 1945, and is buried at Brompton Cemetery, London.
