Ivan Vurnik

Years: 1884-1971 (aged 87)
Occupations: architect
Biography: Ivan Vurnik was a Slovene architect that helped found the Ljubljana School of Architecture. His early style in the 1920s is associated with the search for Slovene "National Style", inspired by Slovene folk art and the Vienna Secession style of architecture (a type of Art Nouveau). Upon embracing the functionalist approach in the 1930s, Vurnik rivaled the more conservative Plečnik's approach. The Cooperative Business Bank, designed by Vurnik and his wife Helena Kottler Vurnik who designed the decorative facade in the colors of Slovene tricolor, has been called the most beautiful building in Ljubljana. Vurnik has also drawn a number of urban plans, among these the plans for Bled (1930), Kranj (1933–1937), and Ljubljana (1935).
