Robert Lundquist Chapman (December 28, 1920 – January 27, 2002) was an American professor of English literature who edited several dictionaries and thesauri. Chapman was born in Huntington, West Virginia to Curtis W. Chapman, a typewriter mechanic, and Cecelia Lundquist Chapman, a homemaker. Chapman graduated from Cooley High School in Detroit, Michigan in 1939. As a young man, he worked in factories and drove a truck, then enrolled at the University of Michigan to study English literature. One of his teachers at Michigan was the poet W.H. Auden. Chapman's college career was interrupted by World War II, when he served in Europe with the United States Army. He returned to Michigan afterwards and received his bachelor's, master's and doctorate degrees.
