Jakob Björck, (1727 or 28 -20/2 1793 in ), was a Swedish portrait painter and copyist.
Björck is reported to have been a pupil of Johan Henrik Scheffel [2], but is not listed as such in the Path Roth's biography. From 1750 to 1774 he worked in pastel painter Gustav Lundberg's studio and then on their own. Married in 1774 by Cicilia Branch born in 1723 or 24, died 16/7 1811 in Stockholm.
In Lundberg's studio 1750-1774 Copies of the oil after Lundberg's pastels are usually routinely attributed Björck, although several other assistants were busy in the studio at the same time; Per Cogell (later city painters in Lyon), Adolf Hall, Jonas Forsslund and a pastel painter named Pettersson. Lundberg also had at times as many orders that he laid out copy orders of other artists - Johan Henrik Scheffel and Fredrik Brander. Moreover, it seems Ulrika Pasch, Olof Arenius and hovminiatyristen John George Henrichsen and Niklas Lafrensen Elder had access to Lundberg's original.
"Björck copies in oil was not infrequently Lundbergs elegance and shimmer surprisingly close," writes Oscar Levertinsgatan in their study. It was well known at that time that the pastel paintings are sensitive to light, moisture and mechanical damage. The 10/1 1760 writes Carl Gustaf Tessin in Åkerö diary: "Mr. Lundberg has Hofintendenten in those days liked to have trouble with my portrait. He and I are born the same year, although not brand neither on its own or eyes. Injury and eternal injury, these portraits are in pastel. " The portraits of Tessin referring to is his own councilors in suit and wife in the yellow dress and black spetsmantilj. Both were shown at the exhibition "The sun and the North Star" at the National Museum 1993-94, however, outside the catalog. They were then heavily faded.
It was therefore common to order copies of the oil from the outset. An example of this is precisely Tessin councilor portrait from 1760, for which Tessin copied Gustaf Lundberg receipt in Åkerö-diary:
"Un portrait original one pastel de Son Excellence Monseignur le Comte de Tessin avec cadre et glace Dlr cuivre 1300
Un ditto the Madame La Comtesse de Tessin 1300
Deux copies one huile you Portrait de Son Excellence à 200 d 400
Deux cadres pour les dite 300 copies
A framed and glazed pastel original cost ie 1300 daler copper coins, equivalent to around SEK 40 000 2009th Framed copies in oil cost 350 crowns copper coins each, representing approximately 11 000 SEK 2009. [6] This may well have been friendly prices because Tessin been Lundberg's patron since the 1720s. By Tessin portraits are ten copies recorded in Swedish Portrait Archive. All have been attributed to Jakob Björck. The same applies to four copies of his wife's portrait, which apparently ordered on another occasion.
