About Vilhelm Assarsson
Lived 1889 – 1974 (aged 85). Vilhelm Assarsson was a Swedish diplomat.
Per Vilhelm Gustaf Assarsson (22 April 1889 – 11 October 1974) was a Swedish diplomat. Assarsson was born in Lund, Sweden, in 1889, the son of a law professor. He graduated with a law degree in 1911 and began his career as a court clerk and district judge. In 1916, he joined the Swedish Ministry for Foreign Affairs, serving as attaché in Copenhagen and Berlin. Over the years, he held key diplomatic positions, including acting legation secretary in Berlin, head of Sweden's first political bureau, and legation counsellor in Washington, D.C. He became a resident envoy to Peru in 1935, accredited to several Latin American countries, and later served in Moscow, where he was involved in trade negotiations with the Soviet Union.
In 1943, Assarsson was declared persona non grata by the Soviet Union and returned to Sweden. He was later appointed deputy state secretary for foreign affairs and played a significant role in the restoration of the Arvfurstens palats, the ministry's headquarters. He retired in 1955 after a long diplomatic career.

Career
Diplomatic career Assarsson became an attaché at the Swedish Ministry for Foreign Affairs in 1916, serving in Copenhagen and Berlin the same year.
On 17 December 1943, Assarsson was declared persona non grata. The official reason given was that the Swedish military attaché, Captain , had allegedly passed Soviet military secrets to Germany. Assarsson returned to Stockholm in February 1944. The Swedish government struggled to interpret the Soviet actions, and upon his return, Assarsson was appointed deputy state secretary for foreign affairs—a position created specifically for him as a demonstration of the government's continued trust. During the first half of 1945, he intermittently served as acting state secretary for foreign affairs, as the regular state secretary, Erik Boheman, was also serving as Sweden's envoy in Paris.
Assarsson himself was convinced that his expulsion was purely a retaliatory move in response to Sweden's refusal to release and repatriate V. Sidorenko, the head of Intourist in Stockholm, who had been exposed as the leader of a Soviet spy ring. When the Swedish government repeatedly refused to comply with Soviet demands, Assarsson and his military attaché were expelled from Moscow in December 1943. The Swedish government then quietly began preparations for Sidorenko's release. A clemency request was submitted to the Supreme Court, which rejected it on 14 January 1944. However, the Swedish government had already prepared the pardon, scheduled for March. This revealed a disconnect between Sweden's political and judicial authorities. Moscow lost patience. On 22 February, bombs fell over Stockholm and Strängnäs. Three days later, Sidorenko was pardoned. He and his wife were swiftly and discreetly flown out of Sweden.
In April 1954, Assarsson was newly elected to the board of B.A. Hjorth & Co. He also served as a board member of the Tessin Society (Tessinsällskapet) until 1959, as well as AB Bacho and Contactor Co.
Personal life Assarsson owned on southern Djurgården in Stockholm from 1944. In 1954, he donated it to the Swedish Academy, intending for it to serve as an honorary residence for the Academy's Permanent Secretary or another member.
Beyond his diplomatic career, Assarsson was also known as a collector of art and curiosities, including antique silver, 18th-century paintings, and antique furniture. He held the Swedish record for the highest number of Grand Crosses—27 in total.
In 1963, he published his memoir, In the Shadow of Stalin, in which he recounted his experiences as Sweden's envoy in Moscow from 1940 to 1944.
Death Assarsson died on 11 October 1974 in Oscar Parish in Stockholm, Sweden.
Awards and decorations In 1963, it was reported that Assarsson held the Swedish record for the highest number of Grand Crosses—27 in total.
By 1972, it was reported that Assarsson had 29 distinctions, including 21 Grand Crosses.
