Sunand Tryambak Joshi (born 22 June 1958) — known as S. T. Joshi — is an award-winning Indian American literary critic, novelist, and a leading figure in the study of Howard Phillips Lovecraft and other authors of weird and fantastic fiction. Besides having written what critics such as Harold Bloom and Joyce Carol Oates consider to be the definitive biography of Lovecraft, I Am Providence: The Life and Times of H.P. Lovecraft (Hippocampus Press, 2 vols., 2010 ), Joshi has prepared (with David E. Schultz) several annotated editions of works by Ambrose Bierce. He has also written on crime novelist John Dickson Carr and on Lord Dunsany, Algernon Blackwood and M. R. James, and has edited collections of their works, as well as collections of the best work of several other weird writers. He is a significant bibliographer, having compiled bibliographies of Lovecraft, Bierce, Dunsany, Ramsey Campbell, William Hope Hodgson (forthcoming), Ray Bradbury and Clark Ashton Smith. He has been general editor of the Horror Classics series for Dover Publications. Joshi is known for his acerbic style, and has been described by editor Ellen Datlow as 'the nastiest reviewer in the field'. Most recently he has turned his attention to collecting and editing the works of H. L. Mencken. He currently resides in Seattle, Washington.
