Joakim Daniel Wahrendorff was from a Westphalian family which had settled in Mecklenburg. He left Germany for Sweden in the middle of the 18th century and became an extremely wealthy foundry owner, known for his contributions to the development of the rifled canon. Bossi painted a different portrait of Wahrendorff and his wife Maria Juliana Rothstein (1736-1821) in 1798. This pair was lent by Baron August Ridderstolpe to the exhibition Äldre Svenska Porträtt-Miniatyrer, Stockholm, Bukowskis, 1915, nos. 264 and 265, and is now in the Swedish National Portrait Gallery's collection (inv. NMGRH 4306 and 4307), featured as a new acquisition in Art Bulletin of Nationalmuseum Stockholm, vol. 9, 2002, p. 37, illustrated in colour p. 38, fig. 17, 18.
