Donald Johnson Greene (November 21, 1914 – May 13, 1997) was a literary critic, English professor, and scholar of British literature, particularly the eighteenth-century period. Known especially for his work on Samuel Johnson, he also wrote on later authors such as Jane Austen, Evelyn Waugh, Graham Greene, and Donald Davie.
Greene was born in Moose Jaw, Saskatchewan, Canada. He began teaching in rural elementary schools and was a non-degreed teacher in Saskatchewan and Alberta. World War II interrupted his academic pursuits; from 1941 to 1945 Greene was a lieutenant and captain in the Royal Canadian Artillery. Following the war he received a graduate fellowship from the Imperial Order of the Daughters of the Empire, and he received his M.A. in 1948 at the University College, London. He twice received a Guggenheim Fellowship, in 1957 and 1979.
Greene had achieved a considerable scholarly contribution even before graduating, with commentary on Samuel Johnson appearing in Notes and Queries, PMLA, Modern Language Notes, and the Review of English Studies. Later, he was the editor of Eighteenth-Century Studies and Johnsonian News Letter, along with holding the position as president of the Johnson Society and served on the board of directors for the Johnson Society of Southern California.
