Born in Prague, July 3, 1883, the son of Hermann and Julie Kafka. 

 The oldest, he had three   surviving younger sisters. Valli, Elli, and Ottla. His father was a self-made middle class   Jewish merchant, who raised his children in the hope of assimilating them into the mainstream   society of the Austro-Hungarian Empire. The official ruling language of the empire was German,   so Franz attended German grammar school (Volksschule am Fleischmarkt), and later the German   Gymnasium (Altstadter Deutsches Gymnasium).
  
He finished his Doctorate of Law in Prague,   studying at the German language University (Die deutsche Universitat) there. He initially   gained employment at a private insurance firm Assicurazioni Generali and then with the   Arbeiter-Unfall-Versicherungs-Anstalt fur das Konigreichs Bohmen in Prag.
  
His Job at the   Worker's Accident Insurance provided him with a steady income and 'regular' office hours,  

   so that he could dedicate his evenings to writing. His diaries contain continuing accounts   of his restlessness and sleeplessness, as he would work all night writing, only to return   to the office for the next day of work, thoroughly exhausted. Although he spoke and wrote   Czech fluently throughout his life, his literary work was all completed in German. He is   known to have started writing at an early age, but all of his earliest attempts were later   destroyed. His first published work came in 1907, and he continued to publish throughout the   next seventeen years, but most of his works were published posthumously by his friend Max   Brod.
Kafka's relationship to his father dominates all discussions of both his life and his work. See his Brief and den Vater to get a feel for the relationship between the thin,   intellectual, and awkward Franz, and the robust, loud, and military corporal Father. 
The   ideas of 'father' and 'family' permeate the fabric of many of Kafka's texts, either directly   as in 
"Das Urteil"   or 
"Die Verwandlung" or more abstractly as in the cases of his two novels 
"The Trial"   and 
"The Castle" (which remained unpublished during his lifetime).
