Wilhelm Christophersen was born at
Brevik in
Telemark, Norway. The son of a customs official in the town, he was a brother of
Christian Christophersen and
Peter Christophersen and the grand-uncle of
Erling Christophersen. In June 1876, he married Swedish citizen Berta Alexandra Juliane Carola Juhlin-Dannfelt (1856–1943). From 1857 he worked in the
Ministry of Auditing, but in 1859 his language skills got him an assignment within the
Ministry of the Interior's office for trade and consular affairs. In 1864 he was transferred to the
Swedish-Norwegian foreign service. He served as consul in
Barcelona from 1864 and in
Buenos Aires from 1868 to 1870, and then as consul-general in the same city until 1878. Having secured this position, he was stationed in
Paris;
Leith,
Scotland; and
Antwerp. Upon the dissolution of the union between Norway and Sweden in 1905, he stayed in Antwerp in the same position, only for the Norwegian government. In March 1908, he was appointed as
Minister of Foreign Affairs in the
first cabinet of
Gunnar Knudsen, where he served until February 1910, when the cabinet resigned. ==Legacy==
