William Makepeace Thackeray was an English novelist, satirist, and journalist, best known for his keen social commentary and his novel Vanity Fair (1847–1848). His works often explored themes of ambition, hypocrisy, and the moral failings of British society, making him one of the most significant literary figures of the Victorian era. Born in Calcutta, British India, he was sent to England for his education after his father’s death. He attended Charterhouse School, where he developed a distaste for the rigid school system, and later enrolled at Trinity College, Cambridge. However, he left without earning a degree, instead traveling in Europe and pursuing artistic ambitions. After losing much of his inheritance due to bad investments, Thackeray turned to writing for a living. He contributed satirical sketches, essays, and stories to periodicals such as Fraser’s Magazine and Punch, gradually building a reputation for his sharp wit and keen observational skills. His breakthrough came with Vanity Fair, a panoramic satire of English society that introduced the enduring character of Becky Sharp, a resourceful and amoral social climber. Thackeray’s later novels, including Pendennis (1848–1850), The History of Henry Esmond (1852), and The Newcomes (1853–1855), continued to explore the lives of the English upper and middle classes, often focusing on the contrast between personal virtue and social ambition. His historical novel Henry Esmond was particularly praised for its detailed 18th-century setting and complex characterization. In addition to his fiction, Thackeray was a noted public speaker and essayist, delivering lectures on the English humorists of the 18th century and on The Four Georges, a critical look at the British monarchy. Despite his literary success, he lived with personal struggles, including the mental illness of his wife, Isabella, which deeply affected him. He remained devoted to his two daughters and was known for his kindness and generosity among his friends and colleagues. His works remain widely read, appreciated for their incisive humor, rich characterizations, and unflinching critique of social pretensions.
