Franz Kafka Austria–Hungary. His unique body of writing—much of which is incomplete and which was mainly published posthumously—is considered to be among the most influential in Western literature.His stories include The Metamorphosis (1912) and In the Penal Colony (1914), while his novels are The Trial (1925), The Castle (1926) and Amerika (1927).Kafka's first language was German, but he was also fluent in Czech. Later, Kafka acquired some knowledge of French language and culture; one of his favorite authors was Flaubert.Kafka first studied chemistry at the Charles-Ferdinand University of Prague, but switched after two weeks to law. This offered a range of career possibilities, which pleased his father, and required a longer course of study that gave Kafka time to take classes in German studies and art history. At the university, he joined a student club, named Lese- und Redehalle der Deutschen Studenten, which organized literary events, readings and other activities. In the end of his first year of studies, he met Max Brod, who would become a close friend of his throughout his life, together with the journalist Felix Weltsch, who also studied law. Kafka obtained the degree of Doctor of Law on 18 June 1906 and performed an obligatory year of unpaid service as law clerk for the civil and criminal courts.Kafka's writing attracted little attention until after his death. During his lifetime, he published only a few short stories and never finished any of his novels, unless "The Metamorphosis" is considered a (short) novel. Prior to his death, Kafka wrote to his friend and literary executor Max Brod: "Dearest Max, my last request: Everything I leave behind me ... in the way of diaries, manuscripts, letters (my own and others'), sketches, and so on, [is] to be burned unread." Brod overrode Kafka's wishes, believing that Kafka had given these directions to him specifically because Kafka knew he would not honor them—Brod had told him as much. Brod, in fact, would oversee the publication of most of Kafka's work in his possession, which soon began to attract attention and high critical regard.Max Brod encountered significant difficulty in compiling Kafka's notebooks into any chronological order as Kafka was known to start writing in the middle of notebooks, from the last towards the first, etc.All of Kafka's published works, except several letters he wrote in Czech to Milena Jesenská, were written in German.
