Jørn Oberg Utzon, AC, Hon. FAIA (Danish: [jɶɐ̯n ˈud̥sʌn]; 9 April 1918 – 29 November 2008) was a Danish architect, most notable for designing the Sydney Opera House in Australia. When it was declared a World Heritage Site on 28 June 2007, Utzon became only the second person to have received such recognition for one of his works during his lifetime. Other noteworthy works include Bagsværd Church near Copenhagen and the National Assembly Building in Kuwait. He also made important contributions to housing design, especially with his Kingo Houses near Helsingør.
Utzon was born in Copenhagen, the son of a naval architect, and grew up in Aalborg, Denmark, where he became interested in ships and a possible naval career. As a result of his family's interest in art, from 1937 he attended the Royal Danish Academy of Fine Arts where he studied under Kay Fisker and Steen Eiler Rasmussen. Following his graduation in 1942, he joined Gunnar Asplund in Stockholm where he worked together with Arne Jacobsen and Poul Henningsen. He took a particular interest in the works of American architect Frank Lloyd Wright. After the end of World War II and the German Occupation of Denmark, he returned to Copenhagen.
