AFTER A DESIGN BY JOSEF HOFFMANN FOR THE PURKERSDORF SANITORIUM, 1904, MANUFACTURED BY J. & J. KOHN, MODEL 322F, CIRCA 1905

It is quite possible that this armchair was specifically Hoffmann's design and not merely a commercial variation by Kohn of Hoffmann's Purkersdorf side chair (See Lots 26/27). There is a precedent for Hoffmann himself developing a side chair into a seat with arms: he is credited as the designer of a two-seat bench with arms (shown at the Kunstschau, Vienna, in 1908), which was a development of his 1906 design for a side chair, (this in turn was offered as a single armchair variant in the Kohn catalogue of that same year, model no. 371F).

Cf: Ostergard, op. cit., No. 54, p. 255, the relationship between the Kunstschau bench and its sidechair and armchair variants discussed.
