Moses Tyson (born 1897, Westmorland; died 1969), was a British historian and librarian who was Keeper of Western Manuscripts at the John Rylands Library from 1927 to 1935 and then Librarian of the Manchester University Library from 1935 until 1965.
[1] His successor Frederick William Ratcliffe described him as "one of the great unsung figures of the University"; according to Brian Pullan, historian of the University, Dr Tyson was "a painfully shy bachelor who shunned the company of women" and "the self-effacing, misogynistic, chain-smoking Librarian".
[2] His friends included Sir William Watson the poet and H. B. Charlton, Professor of English Literature at the University of Manchester.
Tyson was a Member of the Chetham Society, and served as a Member of Council (1934-58) and as Secretary (1940-51).
[3] He was also a Member of the Manchester Literary and Philosophical Society.
