Stefan, Prince Lubomirski was a prominent Polish aristocrat and landowner. In 1905 he became deputy chairman of the Warszawa Philharmonic Orchestra, and in 1917 he co-founded the Inter-Party Political Circle, serving as leader of the National Block prior to Polish independence. Lubomirski was not known to be an IOC Member until this was discovered in 1988 by IOC Historian Wolf Lyberg. He was succeeded on the IOC by Kazimierz Lubomirski, and they were considered to be one person, but Lyberg unearthed letters from Stefan asking that he be replaced on the IOC. The Lubomirskis were only distantly related. Stefan, Prince Lubomirski was co-opted onto the IOC in June 1921 and served less than two years, resigning in April 1923, never having attended an IOC Session.
