Jean Jahnsson

Bror Johan (Jean) Teodor Jahnsson (7 September 1854 in Stockholm – 5 March 1944) was a Swedish jeweller, art collector and Consul General.

Jahnsson acquired the old aristocratic Van der Nootska Palace in Stockholm in 1902, which had long been standing and fallen, and saved it from demolition by ensuring it undergo a complete restoration in consultation with a commission of architects which included Isak Gustaf Clason, Kasper Salin and Agi Lindegren and painter Vicke Andrén; it was the latter two who carried out the restoration.

Jahnsson was hit hard by the Kreuger crash in the early 1930s, in which he was stripped of his wealth and forced to leave the Van der Nootska Palace and auction off most of the collections.

[2] Stensund Castle was sold to Carl Matthiessen, 1933, and the weapons collection auctioned off .

The remainder of Jahnsson's collections from Van der Nootska, which mainly consisted of the Stockholmiana Collection, were donated in 1942 to the Stockholm City Museum of Axel Wenner-Gren, who in February 1938, had bought the Van der Nootska Palace.
