Winifred V. Jackson was a collaborator with Howard Phillips Lovecraft on the short stories, The Green Meadow and The Crawling Chaos, under the name Elizabeth Berkeley. Details about her life are scarce, but there is speculation that she and Lovecraft were romantically involved during the period of their collaborations. Lovecraft was highly congratulatory of her work and praised her talent in his essay, Winifred Virginia Jackson: A "Different" Poetess.
After her divorce from Horace Wheeler Jordan and during her maybe-romance with Lovecraft, she was romantically involved with the African-American poet and critic William Stanley Braithwaite. Some of the remaining examples of her poems appear in his collections.
