Ivan Vurnik (1 June 1884 – 8 April 1971) was a Slovenian architect recognized for co-founding the Ljubljana School of Architecture. Initially, his architectural style in the 1920s focused on establishing a distinct Slovenian "National Style," drawing inspiration from Slovenian folk art and the Vienna Secession architectural movement (a form of Art Nouveau). Transitioning to functionalism in the 1930s, Vurnik diverged from the more traditional approach of Plečnik. Notably, the Cooperative Business Bank, designed by Vurnik, alongside his wife Helena Kottler Vurnik, who created its decorative facade reflecting the colors of the Slovenian tricolor, has been acclaimed as Ljubljana's most exquisite building. Vurnik's contributions extended to urban planning, encompassing projects such as plans for Bled (1930), Kranj (1933–1937), and Ljubljana (1935).
