Cause of death: heart attack
Jørn Oberg Utzon (Danish: [ˈjɶɐ̯ˀn ˈutsʌn]; 9 April 1918 – 29 November 2008) was a Danish architect. In 1957, he won an international design competition for his design of the Sydney Opera House in Australia. Utzon's revised design, which he completed in 1961, was the basis for the landmark, although it was not completed until 1973.
When the Sydney Opera House 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, after Oscar Niemeyer. 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 attended the Royal Danish Academy of Fine Arts (1937–42) and was influenced early on by Gunnar Asplund and Alvar Aalto.
