Answer: LARKIN
Explanation: Librarian and rhymester, Kingston-upon-Hull's ill-humoured notable, primarily? (6)
The 'primarily' clue, treating the hyphens as forming single words; a potted biography of the poet Philip Larkin, although he moved about quite a bit, and only lived the latter part of his life in Hull (he was the Librarian of the Uniiversity of Hull). He was also a jazz critic, and a fellow alumnus of St.John's, Oxford.
