Famed Russian author (7)
I believe the answer is:
tolstoy
(Other definitions for tolstoy that I've seen before include "He wrote Anna Karenina" , "Count Leo . . . . . . . wrote 'War and Peace'" , "Author of Anna Karenina, d.1910" , "Great Russian author of 'War and Peace'" , "Russian writer, 1828-1910" .)
