In 1949, Princess 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[citation needed]. 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. Due to such a collaboration the Gulbenkian Science Institute was born and it promotes scientific research in various areas since the 1950s to date.
