Kurt Georg Kiesinger (* April 6th, 1904 in Ebingen, then-Kingdom of Württemberg) has studied Laws. Since 1933, he's a member of the NSDAP, but (what's uncommon) not a member of the NS-Rechtswahrerbund (the Nazi lawyers guild). In 1939/40, for some time he was a Blockwart (Nazi functionary overseeing some dozen households). Since 1940, he works for the Auswärtiges Amt (Foreign Ministry).
His Mother died half a year after his birth. On December 24th in 1932, Kiesinger married Marie-Luise Schneider (* 1908) in Berlin.
