Musicians.
Family portrait formerly regarded as the Bach Family, attributed to Balthasar Denner 
in oils, on canvas, unsigned, in an eighteenth-century gilt frame, overall dimensions 117.8 x 101.6cm, unframed dimensions 79.8 x 63.8cm, on the back of the frame the vestiges of two labels, one with the number 1249, the other reading "Münchener Jahres Ausstellung 1899 im Glaspalast Nr. 2737 Name des Absenders...Wohnung", no place, possibly early 1730s 
Before its appearance at the auction of Old Master Paintings at Sotheby's in July 1996, this fine portrait depicting a family of four musicians - a middle-aged man holding in amateurish fashion a four-stringed violoncello (evidently from central Germany, c.1730s), a young boy with a violin, an older boy holding a transverse flute, and a still older youth also holding a violin - had remained in a German collection and was unknown to the wider world, although at least one of the two labels on the frame hints at some nineteenth-century public exposure, in a Munich exhibition in 1899.
Both this portrait, and a less finished, less brilliant, version of this painting attributed to the leading German portraitist of the day, Balthasar Denner (1685-1749), and now in the Landesmuseum Württemberg, Stuttgart, have been held variously to represent the Bach family, even possibly the Abel family of musicians. A number of objections however can be raised to both of these identifications - regarding for instance the ages and identities of the possible sitters - which rule out in our opinion the depiction of either musical family. As far as the Bach family is concerned, one only need wonder why the leading organist and harpsichordist of his day, J.S. Bach, should be depicted holding a violoncello (the wrong way round). Yet whoever may be depicted in the Kohn portrait, it remains a highly interesting, if tantalising, image of an eighteenth-century family of musicians, full of research potential, and whose ultimate identification will one day surely come.
We are pleased to acknowledge the kind assistance of Teri Noel Towe and Thomas Fritzsch in our cataloguing of this lot.
