Infanta Maria Adelaide of Portugal  Doña Maria Adelaide of Braganza, Infanta of Portugal, (31 January 191224 February 2012) was a member of the royal house of Braganza, daughter of Miguel, Duke of Braganza and Princess Maria Theresa of Löwenstein-Wertheim-Rosenberg. Infanta Maria Adelaide was born in Saint-Jean-de-Luz, France. Her godparents were King Manuel II, the last reigning king of Portugal (deposed in 1910), and his mother Queen Amélie. She was educated at the Sacre Coeur College in Riedenburg, Germany. She was married in Vienna, 13 October 1945, to Dr. Nicolaas van Uden (Venlo, 5 March 1921 – Lisbon, 5 February 1991) who was Dutch and who became a naturalized Portuguese citizen in 1975. Son of Adrian van Uden (Gerwen, 7 May 1893 – 24 December 1959) and wife Cornelia Antonia Baaijeens (Gorinchem, 7 September 1897 – 15 June 1979), daughter of Nicolaas Baaijeens and wife Helena Dam, Nicolaas van Uden was a medical biochemist and a great scientific authority in the field of yeast development. Infanta Maria Adelaide lived in Vienna, Austria, working as a nurse and social assistant. During World War II, when there were bombardments, she travelled at night to the place to provide aid to the victims. She was part of the Nazi resistance movement, and the Gestapo sentenced her to death. The Portuguese President of the Council of Ministers, António de Oliveira Salazar intervened with the Germans, claiming that Infanta Maria Adelaide was a national heritage. This intervention of the Portuguese diplomacy resulted in the release and her immediate deportation, after which she settled in Switzerland. It was there that her brother Dom Duarte Nuno, Duke of Braganza lived with his wife Francisca. After the war, the family finally returned to Austria. In 1949, Dona Maria Adelaide settled in Portugal. Meanwhile, her husband graduated in medicine from the University of Vienna and specialized in diseases of the skin. But when Dr. Nicolaas van Uden arrived in Portugal his qualifications were not recognised as equivalent to the Portuguese ones, and therefore he could not practice medicine. As there was no other solution, he went to work for a small research laboratory at the Faculty of Science and stayed there for several years, until the opportunity to work in partnership with the Calouste Gulbenkian Foundation arose.
