Sigvard Bernadotte /

Sigvard Oscar Fredrik Bernadotte, Count of Wisborg (Drottningholm, 7 June 1907 – Stockholm, 4 February 2002) was a Swedish industrial designer. He was the second son of King Gustaf VI Adolf of Sweden and his first wife, Princess Margaret of Connaught and was originally known as Prince Sigvard, Duke of Uppland, but lost his royal titles in 1934 when he married a commoner. He married three times; on 8 March 1934 in London he married commoner Erica Maria Patzek (Wilmersdorf, 12 July 1911-Wilmersdorf, 20 July 2007), daughter of Anton Patzek and wife Marie Anna Lala, and because it was an unequal match, regardless of whether the monarch was willing to consent to the marriage, he lost his princely title and was excluded from the line of succession. Sigvard and Erika had no children and divorced on 14 October 1943. Only 12 days later on 26 October in Copenhagen he married another commoner, Sonja Christensen Robbert (Copenhagen, 12 October 1909 – 21 May 2004), daughter of Robert Alexander Christensen Robbert and wife Ebba Elisabeth Svenson. They had a son, Count Michael Sigvard Bernadotte af Wisborg, born in Copenhagen on 21 August 1944. Sigvard and Sonja were divorced on 6 June 1961. A
