He held a Guggenheim Fellowship in 1939 and in 1945. His scholarship was interrupted during World War II, when he worked for the Bureau of the Budget and served in the U.S. Army.
In 1946 Mossner joined the English faculty of the University of Texas at Austin, serving for several years as editor of Texas Studies in Language and Literature. While on a Fulbright Research Fellowship in 1968 he was a visiting professor at Glasgow University, where he would later become a member of a committee established by the University to edit a scholarly edition of the works of Adam Smith. In 1970 he was named Ashbel Smith Professor of English and Philosophy at the University of Texas. He retired from teaching in 1972, and in 1976 received the honorary D.Litt. from Edinburgh University.
