Duke Stefan of Habsburg Lothringen, the eldest sun of Duke Anton of Austria and Princess Ileana of Romania (Mother Alexandra as she was known after joining an orthodox monastery; daughter of Queen Maria and King Ferdinand and sister of King Carol II) died of cancer at age 64. He was born in Austria, near Vienna, and he spent his last years in USA. He knew Romanian language perfectly, being raised by his mother, Princess Ileana and her second husband Stefan Isarescu, who now lives near New Jersey.

According to the 1923 Romanian Constitution, he was the presumptive heir of the Romanian throne, if his cousin, King Mihai, did not have any sons. In December 1997, King Mihai designated his daughter, Princess Margareta, as heir of his prerogatives as monarch. Stefan of Habsburg never claimed the throne for himself, being in excellent relations with King Mihai.
