Mary Amelia St. Clair (1863-1946) was a British writer and suffragist who wrote under the pseudonym of May Sinclair. Both a successful writer and important literary critic, Sinclair supported herself and her mother. She was a prominent critic of modernist poetry and prose, and has been credited for being the first to use "stream of consciousness" in a literary context. Sinclair was very socially active, advocating for scientific advancements and participating in suffrage movements. She often included feminist themes in her work, encouraging discussion on the social disadvantages forced on women. After her death in 1946, Sinclair left behind a legacy of innovative literary critiques, impactful activism, and a vast literary canon.
