Logothetopoulos studied medicine in
Munich and remained in the
German Empire, practicing and teaching medicine until 1910, at which time he relocated to
Athens. In Greece, he founded a private clinic and served in both the
First Balkan War (1912–1913) and the
Second Balkan War (1913) as a doctor. He was discharged in 1916, resuming private medical practice until 1922 when he was again conscripted during the
Greco-Turkish War to serve in the Army Hospital of Athens. After the end of the war in 1922, Logothetopoulos became professor of
gynaecology at the
National and Kapodistrian University of Athens. Eventually he became Dean of the University. During his tenure at the university, he taught and assisted many young doctors in their studies including future politician
Grigoris Lambrakis. When Greece capitulated to
Nazi Germany after the "
Battle of Greece" during
World War II, Logothetopoulos, who spoke the
German language fluently, had been the chairman of the Greek-German Council and was married to the niece of
Field Marshal Wilhelm List, was appointed Vice President and Minister of Education in the first collaborationist government of Gen.
Georgios Tsolakoglou. After Tsolakoglou was removed from office, he served as Prime Minister between 2 December 1942 and 7 April 1943, when he was replaced by
Ioannis Rallis. His short tenure was marked by the start of the deportation of Greek Jewry, in which he played an ambiguous role. When the
Wehrmacht left Greece in 1944, Logothetopoulos went with them to Nazi Germany. He lived with his wife and daughter in the small Bavarian town of
Vilshofen an der Donau, where he practiced medicine. Eventually he was captured by the
United States Army which surrendered him to Greek authorities in 1946. He was tried and convicted of
collaborating with the enemy and initially sentenced to
life imprisonment, but was released in 1951. ==Death==
