Anton Pavlovich Chekhov (/ˈtʃɛkɒf/; Russian: Антон Павлович Чехов, IPA: [ɐnˈton ˈpavləvʲɪtɕ ˈtɕexəf]; 29 January 1860 – 15 July 1904) was a Russian playwright and short-story writer, widely considered to be one of the greatest writers of all time. His career as a playwright produced four classics, and his best short stories are held in high esteem by writers and critics. Along with Henrik Ibsen and August Strindberg, Chekhov is often referred to as one of the three seminal figures in the birth of early modernism in the theatre. Chekhov was a physician by profession. "Medicine is my lawful wife," he once said, "and literature is my mistress."

Chekhov renounced the theatre after the reception of The Seagull in 1896, but the play was revived to acclaim in 1898 by Konstantin Stanislavski's Moscow Art Theatre, which subsequently also produced Chekhov's Uncle Vanya and premiered his last two plays, Three Sisters and The Cherry Orchard. These four works present a challenge to the acting ensemble as well as to audiences, because in place of conventional action Chekhov offers a "theatre of mood" and a "submerged life in the text." The plays that Chekhov wrote were not complex, and created a somewhat haunting atmosphere for the audience.

Chekhov began writing stories to earn money, but as his artistic ambition grew, he made formal innovations that influenced the evolution of the modern short story. He made no apologies for the difficulties this posed to readers, insisting that the role of an artist was to ask questions, not to answer them.

Anton Pavlovich Chekhov was born on the feast day of St. Anthony the Great (17 January Old Style) 29 January 1860 in Taganrog, a commercial port city on the Sea of Azov – on Politseyskaya (Police) street, later renamed Chekhova street – in southern Russia. He was the third of six surviving children; he had two older brothers, Alexander and Nikolai, and three younger siblings, Ivan, Maria, and Mikhail. His father, Pavel Yegorovich Chekhov, the son of a former serf and his wife, was from the village Olkhovatka (Voronezh Governorate) and ran a grocery store. He was a director of the parish choir, a devout Orthodox Christian, and a physically abusive father. Pavel Chekhov has been seen by some historians as the model for his son's many portraits of hypocrisy. Chekhov's mother, Yevgeniya (Morozova), was an excellent storyteller who entertained the children with tales of her travels all over Russia with her cloth-merchant father. "Our talents we got from our father," Chekhov recalled, "but our soul from our mother."

Young Chekhov attended the Greek School in Taganrog and The Taganrog Boys Gymnasium (since renamed the Chekhov Gymnasium). There he was held back for a year at fifteen for failing an examination in Ancient Greek. He sang at the Greek Orthodox monastery in Taganrog and in his father's choirs. In a letter of 1892, he used the word "suffering" to describe his childhood and recalled:

When my brothers and I used to stand in the middle of the church and sing the trio "May my prayer be exalted", or "The Archangel's Voice", everyone looked at us with emotion and envied our parents, but we at that moment felt like little convicts.

Later, in his adulthood, Chekhov criticized his brother Alexander's treatment of his wife and children by reminding him of their father Pavel's tyranny: "Let me ask you to recall that it was despotism and lying that ruined your mother's youth. Despotism and lying so mutilated our childhood that it's sickening and frightening to think about it. Remember the horror and disgust we felt in those times when Father threw a tantrum at dinner over too much salt in the soup and called Mother a fool."

In 1876, Chekhov's father Pavel was declared bankrupt after overextending his finances building a new house, having been cheated by a contractor named Mironov. To avoid debtor's prison he fled to Moscow, where his two eldest sons, Alexander and Nikolai, were attending university. The family lived in poverty in Moscow. Chekhov's mother was physically and emotionally broken by the experience.
