Bukowski's parents met in Andernach, Germany, following World War I. The poet's father was German-American and a sergeant in the United States Army serving in Germany after Germany's defeat in 1918. He had an affair with Katharina, a German friend's sister, and she became pregnant. Charles Bukowski repeatedly claimed to be born out of wedlock, but Andernach marital records indicate that his parents married one month before his birth. Afterwards, Henry Bukowski became a building contractor, set to make great financial gains in the aftermath of the war, and after two years moved the family to Pfaffendorf (today part of Koblenz). However, given the crippling postwar reparations being required of Germany, which led to a stagnant economy and high levels of inflation, Henry Bukowski was unable to make a living, so he decided to move the family to the United States. On April 23, 1923, they sailed from Bremerhaven to Baltimore, Maryland, where they settled.
