Witold Dederko (1906-1988) was a descendant of well-known photographers - son of Marian Dederko, who developed the photogum and photonite techniques, and grandson of Soter Dederko. With his father he ran an author's company, which operated until 1930 and briefly after 1945. They also exhibited their works together from 1924. Both used the photonite method, which was an amalgam of two disciplines: photography and painting. From 1929 he worked at the Polish Telegraphic Agency, and from 1935 he was head of Kodak's Warsaw laboratory. After the war, he taught at the National Film and Theater School in Lodz. Author of more than a dozen books on photography. During meetings with young people in Staromiejski cafes, he loved to read from a notebook his story about Witkacy. He used to say of himself "the last shaman of the Republic."
