The Metamorphosis is a novella written by Franz Kafka which was first published in 1915. One of Kafka's best-known works, The Metamorphosis tells the story of salesman Gregor Samsa who wakes one morning to find himself inexplicably transformed into a huge insect (German ungeheures Ungeziefer, literally "monstrous vermin"), subsequently struggling to adjust to this new condition. The novella has been widely discussed among literary critics, with differing interpretations being offered.

Franz Kafka (3 July 1883 – 3 June 1924)a German-speaking Bohemian novelist and short-story writer, widely regarded as one of the major figures of 20th-century literature. His work fuses elements of realism and the fantastic. It typically features isolated protagonists facing bizarre or surrealistic predicaments and incomprehensible socio-bureaucratic powers. It has been interpreted as exploring themes of alienation, existential anxiety, guilt, and absurdity. His best known works include "Die Verwandlung" ("The Metamorphosis"), Der Process (The Trial), and Das Schloss (The Castle). The term Kafkaesque has entered the English language to describe situations like those found in his writing.

Kafka was born into a middle-class German-Jewish family in Prague, the capital of the Kingdom of Bohemia, then part of the Austro-Hungarian Empire, today the capital of the Czech Republic. He trained as a lawyer and after completing his legal education was employed full-time by an insurance company, forcing him to relegate writing to his spare time. Over the course of his life, Kafka wrote hundreds of letters to family and close friends, including his father, with whom he had a strained and formal relationship. He became engaged to several women but never married. He died in 1924 at the age of 40 from tuberculosis.

Few of Kafka's works were published during his lifetime: the story collections Betrachtung (Contemplation) and Ein Landarzt (A Country Doctor), and individual stories (such as "Die Verwandlung") were published in literary magazines but received little public attention. In his will, Kafka instructed his executor and friend Max Brod to destroy his unfinished works, including his novels Der Prozess, Das Schloss and Der Verschollene (translated as both Amerika and The Man Who Disappeared), but Brod ignored these instructions. His work has influenced a vast range of writers, critics, artists, and philosophers during the 20th and 21st centuries.
