Jacob Samils Haldeman (October 13, 1821 – November 1889) was an American banker, politician and ambassador from Pennsylvania who served as Minister Resident of the United States at Stockholm from 1861 to 1864.
[1] In March 1861, Abraham Lincoln nominated Haldeman as Minister to Sweden and Norway following a suggestion by Simon Cameron.
On June 14, 1861, Haldeman wrote that "from the limited opportunity I have had to judge, I have no hesitation in the declaration of opinion that the sympathy of the entire North of Europe is almost unanimously in favor of the existing government in the United States.
The emigration of this part of Europe having been to the Northern or free States, they speak of it as if they would like to give active aid to their friends, relations, and countrymen.
The reports concerned immigration from the Scandinavian countries, rumors regarding Confederate activities in the kingdoms of Sweden and Norway and the attitudes of the Swedish people and government towards the Union.
When it was rumored that Confederate representatives were seeking recognition from Sweden, Seward wrote to Haldeman: "The president confidentially relies upon your well-known vigilance and activity as well as upon the friendly disposition of the Swedish government to prevent the carrying into effect of any such design".
