Sadleir, Michael (Thomas Harvey) (1888-1957)

English writer and publisher. His commentaries on Anthony Trollope, Trollope: A Commentary 1927 and Trollope: A Bibliography 1928, were largely responsible for a revival in that author's popularity. He also wrote other works on literary history, the bibliographic survey Nineteenth Century Fiction 1951, and novels, including Fanny by Gaslight 1940.

Sadleir was born and educated in Oxford. In 1912 he entered the publishing firm of Constable, of which he became a director 1920. In 1937 he became reader in bibliography at Cambridge, and in 1944 president of the Bibliographical Society.
