1866-1944 · Austrian-German
Heinrich Kühn (1866-1944) is the Austrian-German pictorialist master who perfected the gum bichromate and gum-over-platinum processes in Innsbruck. A peer of Stieglitz and Steichen, Kühn brought painterly chromatic depth to family portraiture and Alpine landscapes, and pioneered the multi-layer pigment print at monumental scale.
Public domain since 2015 · CPI L.123-1
Held at
Born in Dresden, Kühn settled in Innsbruck (Tyrol) in 1888 and there developed an obsessive mastery of the gum bichromate process — using multiple passes of pigment over a single sheet to achieve unprecedented tonal range and color depth. His family portraits of his children (Hans, Lotte, Walter, Edeltrude) and the family governess Mary Warner form one of pictorialism's most intimate corpora. As a member of the Wiener Kleeblatt (Vienna Trifolium) with Hans Watzek and Hugo Henneberg, and friend of Stieglitz (who published him in Camera Work), Kühn co-defined the international pictorialist project. He also pioneered the gum-over-platinum hybrid (Gummiplatindruck), the bromoil transfer, and was an early adopter of the Lumière Autochrome (1907). Held at Albertina Vienna, MoMA, MET, and Städel Museum Frankfurt. Public domain since 2015. His gum bichromate practice is a direct historical model for Maison Picturale.
