May Sinclair was the pseudonym of Mary Amelia St. Clair (24 August 1863 - 14 November 1946), 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.
