The following thesis examine the former homes of Charlotte Berlin and Wilhelmina von Hallwyl, two women who in the turn of 20th century donated their homes and collections to be museums. The purpose of this essay is to examine how Charlotte Berlin’s Museum and the Hallwyl museum work with musealization and authenticity.Both Charlotte and Wilhelmina lived their life in a changing time, where emigration, industrialization and urbanization took place. They are both women from the upper-middle class but with differences such as economic ones which has an effect of the collection and the size of their homes. Further distinctions between them is that Wilhelmina was married and Charlotte was not. Wilhelmina lived in the capital of Sweden, Charlotte in the small town called Ystad. Their similarities is found in their collections of clocks, clothes, paintings and books but most of all in their determination to make their homes museums once they were gone. They sought to make sure that their changing time could be seen through their collection. By examine how this is visible in the rooms they left 137behind, it is possible to see the relationship between the props and the authentic objects. The signs of it now being a museum, as cordons and glass stands, collaborates with the presence of the former inhabitants as well as movemements, seen through objects like chairs placed slightly obliquely. This essay also establish a new term called affective authenticity, which describe and develop the sensation of the past, the relation between the imagi-nation and the reality and the connection between people, objects and the milieu, with the importance that every-thing does not have to be all authentic, but has to mediate it. This is a two year’s master thesis in Museum and Cultural Heritage Studies.
