Ivan ___, author of the novel Fathers and Sons (8)
I believe the answer is:
turgenev
(Other definitions for turgenev that I've seen before include "Ivan -------- (1818-1883), writer about Russian life as in Fathers and Sons" , "Ivan -, Russian novelist (Fathers and Sons)" , "Dramatist" , "Ivan -, Russian author (A Month in the Country)" , "Russian author (Fathers and Sons, Virgin Soil)" .)
