Man of science tears up novel (7)
I believe the answer is:
pasteur
'man of science' is the definition.
(Pasteur is an example)
'tears up novel' is the wordplay.
'novel' indicates anagramming the letters.
'tears'+'up'='tearsup'
'tearsup' anagrammed gives 'PASTEUR'.
(Other definitions for pasteur that I've seen before include "Louis ---, Fr. bacteriologist" , "Famous bacteriologist" , "He developed the partial sterilization of milk" , "Pioneer immunologist" , "Louis --, French chemist/bacteriologist" .)
