Hugo Henneberg Austro-Hungarian, 1863-1918 Born in Vienna, Hugo Henneberg received his doctorate in physics in the late 1880s. About 1890 he became interested in photography and the following year took part in Vienna's Ausstellung Kunstlerischer Photographien, the first international exhibition of artistic amateur photography. Around the time of his acceptance into the Linked Ring (1894), Henneberg developed a friendship with fellow Austrian pictorialists Heinrich Kuehn and Hans Watzek. They exhibited together under the name the Trifolium (Das Kleeblatt), becoming known for their large-scale gum bichromate prints. Henneberg's photographs, primarily of landscapes, were included in numerous European exhibitions throughout the 1890s and into the first decade of the 20th century. His work was reproduced in Camera Notes and Camera Work and was included in a 1906 showing of Austrian and German photographers at "291," as well as in the 1910 International Exhibition of Pictorial Photography at the Albright Art Gallery, Buffalo. Around 1911 he turned from photography to painting. M.M.
