Leo Nikoleyevich Tolstoy 
Anna Karenina 

"Happy families are all alike; every unhappy family is unhappy in its own way, " writes Tolstoy in his literary masterpiece Anna Karenina. Commonly regarded as one of the greatest realist novels ever written, Tolstoy himself saw it as his first true novel. The novel was not well received by critics when first published, but Tolstoy’s fellow Russian greats all considered it a great work of art.
