Gustaf Oscar Wallenberg (1865-1937), Stockholm, and thence by descent

Gustaf O. Wallenberg was a Swedish businessman, diplomat and active politician. He was the son of André Oscar Wallenberg, founder of Stockholm Enskilda Bank (today's Skandinaviska Enskilda Banken, known as SEB). After a career in the Swedish Navy he turned to the business world and was active in improving the transoceanic shipping industry.

Wallenberg was Sweden's Envoy to Tokyo between 1907-1918. In April 1907 he travelled to Beijing to amend the Treaty of Canton (1847) between Sweden-Norway and China and to establish diplomatic relations between Sweden and the Qing Court. As the Swedish Envoy Extraordinary and Minister Plenipotentiary at the Court of Peking, he successfully negotiated and signed with Lien Fang, the Guangxu Emperor's High Commissioner Plenipotentiary and Senior Vice-President of the Wai Wu Pu, the Treaty of Amity, Commerce and Navigation, between Sweden and China, which was signed in Beijing on 2 July 1908, with an additional article signed on 24 May 1909.
