What's a single word for someone who writes literature?

As the title suggests, what's a single word to call someone who writes literature? (By Literature, I refer to great works such as those written by Keats, Joyce, Faulkner, Bronte, etc.)

Exempli gratia, we call someone who writes poetry a poet, a playwright writes drama etc. So, in general, what do we call someone who writes literature?

(Mathematician+Physicist+Chemist+...)=Scientist

Then, (Poet+Playwright+...)=?

Any help is appreciated.

EDIT: By literature, I mean fictional works such as poetry, play, short-story, novel. Science fiction can also be considered. Some Feynman-esque papers might suffice to fall in the category. Although it excludes text books, scientific papers and the equivalent.


Solution 1:

I'd suggest, litterateur/littérateur

Also, literator n. - One who is devoted to the study or writing of literature FOD

Alternately, how about belletrist and literarian?

belletrist: a writer of belles-lettres FOD

literarian n. — «A literarian is someone who loves literature so much that he or she wants to share it with as many people as possible, so this award is for those who dedicate their lives to love of literature.» —“Taking on the establishment made Ferlinghetti a shoo-in to receive first-ever literarian award” by Heidi Benson San Francisco Chronicle (California) Nov. 16, 2005. (source: Double-Tongued Dictionary) A Way with Words

An educated or lettered person; one engaged in literary pursuits. ODO

James Patterson honored with 2015 Literarian Award National Book Foundation

Solution 2:

I might have misinterpreted your intentions, but I was surprised no one suggested simply author:

One who practices writing as a profession.
