Career
After graduating from a classical gimnazjum in Lviv Wittlin joined the volunteer military formation of the Polish Legion in August 1914. His unit was however soon disbanded due to the refusal of the Poles to take the oath for the Austrian government. Subsequently he went to Vienna, where he passed the Matura and began studying philosophy.
Shortly before being sent to the Italian front he fell ill with scarlet fever and was thus prevented from direct participation in the fighting.
His military service took place far off the front and included among other things working as a translator in Prisoner-of-war camps with Italian soldiers. In 1922 he moved to Łódź and 1927 to Warsaw.
At this time he undertook extensive travels through Europe which significantly influenced his work. At the outbreak of World World War II he lived in Paris, from where he was evacuated in May 1940 to Biarritz.
With the help of Hermann Kesten he and his family succeeded to escape in January 1941 from Nice through Spain and Portugal to New York where he remained after the war.
