Prince Seweryn Franciszek Światopełk-Czetwertyński (pronounced as /pl/; b. 18 April 1873 in Warsaw – 19 June 1945 in Edinburgh, Scotland) was a Polish landowner, entrepreneur and politician. He belonged to a cadet branch of the Czetwertyński family, historically one of the princely houses of Poland and Lithuania.[1]
He was a pupil at the Realschule in Riga and was a member of the Polish student fraternity Arkonia. He went on to study at the University of Bonn.[2]
He became a member of the Russian Duma in 1906, and after Poland had regained its independence, he was elected to the Sejm from 1919 until 1935. During World War II, he was a prisoner of Nazi Germany, and was imprisoned at Buchenwald and Auschwitz concentration camps. He died of exhaustion barely two months after liberation, having newly arrived in the United Kingdom.
Światopełk-Czetwertyński was married to Zofia Przeździecka; their son Włodzimierz (1907–1965) and elder grandchildren were born in Poland, but during World War II, they fled to Britain, eventually taking up residence in North America.[1]
