Notes from Underground is an 1864 novella by Fyodor Dostoyevsky. Notes is considered by many to be the first existentialist novel. It presents itself as an excerpt from the rambling memoirs of a bitter, isolated, unnamed narrator (generally referred to by critics as the Underground Man) who is a retired civil servant living in St. Petersburg. The first part of the story is told in monologue form, or the underground man's diary, and attacks emerging Western philosophy, especially Nikolay Chernyshevsky's What Is to Be Done?. The second part of the book is called "Àpropos of the Wet Snow," and describes certain events that, it seems, are destroying and sometimes renewing the underground man, who acts as a first person, unreliable narrator.

Fyodor Mikhailovich Dostoevsky was a Russian novelist, short story writer, essayist, and journalist. His literary works explore human psychology in the troubled political, social, and spiritual atmospheres of 19th-century Russia, and engage with a variety of philosophical and religious themes. His most acclaimed novels include Crime and Punishment (1866), The Idiot (1869), Demons (1872), and The Brothers Karamazov (1880).

Many literary critics rate him as one of the greatest novelists in all of world literature, as multiple of his works are considered highly influential masterpieces.
