The written estate (9 boxes, 1 large-format folder) contains working materials, travel and excursion diaries, manuscripts, publications, bibliographic index, correspondence with family, friends, acquaintances, colleagues, publishers and other institutions, personal and professional documents, a small proportion of the collection and partial estates of the wife Eva Schmieder (née Pelet), the daughter Elma Schmieder (later: Behrens) and the mother-in-law Maria Pelet. - The extensive photographic estate (10 boxes) contains mostly photographs by Oskar Schmieder, but also partly by other photographers. The photographs were taken in connection with publications, excursions, professional and private journeys, as well as in a family context. The photographic legacy is merely pre-arranged, roughly indexed and contains numerous duplicates.
