WINNERS OF THE NOBEL PRIZE FOR LITERATURE WHO HAVE STUDIED LAW . . . Don't ask me why I bothered to find out how many of the Nobel Prize winners in literature studied or practiced law. But I did. There were more than I thought. How many have you read?
1901 Sully Prudhomme. Took up law "without much conviction" and worked in a solicitor's office.
1902 Theodor Mommsen. Was a law professor at the University of Leipzig.
1904 Frédéric Mistral. Obtained a law degree but didn't practice.
1911 Maurice Maeterlinck. Worked as a lawyer while "demonstrating brilliantly his ineptitude for the legal career, having the happy defects that render a man absolutely unfit for the pettifogging quarrels and public counsel's speeches in the law court."
1919 Carl Spitteler. Studied law at his father's request at the University of Zürich.
1922 Jacinto Benavente. Studied law until his father's death left him with a sizable inheritance.
1932 John Galsworthy. Studied law at New College, Oxford.

I compiled this list myself, so it might be incomplete. If you want to do further research, here's a full list of Nobel Prize winners in literature.
