Kafka writer series#

Much of Kafka's writing was left incomplete and unpublished during his lifetime, with the notable exception of Metamorphosis and several of his short stories.Īlways somewhat frail physically, Kafka developed tuberculosis in 1917 and went through a series of treatments over the next several years. Together with his close friends and fellow writers Max Brod and Felix Weltsch, Kafka formed a Prague writers group which was part of the broader Prague Circle of German-Jewish writers. He went on to work for the Worker's Accident Insurance Institute for the Kingdom of Bohemia - a relatively undemanding job that left him time to write.

The Prague monument was inspired by Kafka's 'Description of a Struggle' Image: AP After starting with chemistry, the young Kafka earned a degree in law at the German-language university in Prague.

His first language was German and all of his literary works were composed in German, but he also spoke fluent Czech. Kafka was born on Jto a middle-class Jewish family in Prague, which was part of the Austro-Hungarian Empire at the time. His main characters lead complicated, nightmarish lives - perhaps not unlike his own - in an impersonal society. Known for his long, drawn-out sentences and penchant for ambiguity - which make his works a real challenge for translators - Kafka authored 'Metamorphosis' (1915), 'The Trial' (1925), 'The Castle' (1926) and a slough of other well-known short stories and novel.
