May Sinclair

May Sinclair was the pseudonym of Mary Amelia St. Clair a popular British writer who wrote about two dozen novels, short stories and poetry. She was an active suffragist, and member of the Woman Writers' Suffrage League. She once dressed up as a demure, rebel Jane Austen for a suffrage fundraising event. Sinclair was also a significant critic in the area of modernist poetry and prose, and she is attributed with first using the term 'stream of consciousness' in a literary context, when reviewing the first volumes of Dorothy Richardson's novel sequence Pilgrimage (1915–1967), in The Egoist, April 1918.

Sinclair was born in Rock Ferry, Cheshire. Her mother, Amelia Sinclair, was strict and religious; her father, William Sinclair, was a Liverpool shipowner, who went bankrupt, became an alcoholic, and died when Sinclair was still a child. The family moved to Ilford on the edge of London. After one year of education at Cheltenham Ladies College, Sinclair was obliged to look after her brothers, as four of the five, all older than her, were suffering from a fatal congenital heart disease.

From 1896 Sinclair wrote professionally to support herself and her mother, who died in 1901. An active feminist, Sinclair treated a number of themes relating to the position of women and marriage. Her works sold well in the United States.

Around 1913, she was a founding supporter of the Medico-Psychological Clinic in London which was run by Dr Jessie Murray. Sinclair became interested in psychoanalytic thought, and introduced matter related to Sigmund Freud's teaching in her novels. In 1914, she volunteered to join the Munro Ambulance Corps, a charitable organization (which included Lady Dorothie Feilding, Elsie Knocker and Mairi Chisholm) that aided wounded Belgian soldiers on the Western Front in Flanders. She was sent home after only a few weeks at the front; she wrote about the experience in both prose and poetry.

Her 1913 novel The Combined Maze, the story of a London clerk and the two women he loves, was highly praised by critics, including George Orwell, while Agatha Christie considered it one of the greatest English novels of its time.

She wrote early criticism on Imagism and the poet H. D. (1915 in The Egoist); she was on social terms with H. D. (Hilda Doolittle), Richard Aldington and Ezra Pound at the time. She also reviewed in a positive light the poetry of T. S. Eliot (1917 in the Little Review) and the fiction of Dorothy Richardson (1918 in The Egoist). Some aspects of Sinclair's subsequent novels have been traced as influenced by modernist techniques, particularly in the autobiographical Mary Olivier: A Life (1919). She was included in the 1925 Contact Collection of Contemporary Writers.

Sinclair wrote two volumes of supernatural fiction, Uncanny Stories (1923) and The Intercessor and Other Stories (1931). E. F. Bleiler called Sinclair "an underrated writer" and described Uncanny Stories as "excellent". Gary Crawford has stated Sinclair's contribution to the supernatural fiction genre, "small as it is, is notable". Jacques Barzun included Sinclair among a list of supernatural fiction writers that "one should make a point of seeking out".Brian Stableford has stated that Sinclair's "supernatural tales are written with uncommon delicacy and precision, and they are among the most effective examples of their fugitive kind." Andrew Smith has described Uncanny Stories as "an important contribution to the ghost story".

Sinclair also wrote non-fiction based on studies of philosophy, particularly idealism. She defended a form of idealistic monism in her book A Defence of Idealism (1917).Sinclair was interested in parapsychology and spiritualism, she was a member of the Society for Psychical Research from 1914.

From the late 1920s she was suffering from the early signs of Parkinson's disease, and ceased writing. She settled with a companion in Buckinghamshire in 1932.

She is buried at St John-at-Hampstead's churchyard, London.
