The DIN system, officially DIN standard 4512 by Deutsches Institut fur Normung (but still named Deutscher Normenausschuss (DNA) at this time), was published in January 1934. It grew out of drafts for a standardized method of sensitometry put forward by Deutscher Normenausschuss fur Phototechnik as proposed by the committee for sensitometry of the Deutsche Gesellschaft fur photographische Forschung since 1930 and presented by Robert Luther (de) (1868-1945) and Emanuel Goldberg (1881-1970) at the influential VIII. International Congress of Photography (German: Internationaler Kongress fur wissenschaftliche und angewandte Photographie) held in Dresden from August 3 to 8, 1931.
