In post-humanist studies of identity, otherness and exclusion – conducted within the de-anthropocentrism of the humanities – questions arise about the condition of non-human subjects (animals, plants, things) that gain the cultural and social status of Others. As non-human entities, they have a socializing value, cement interpersonal relations, attract people to certain places. They have performative, integrative and co-creating abilities. The posthumanistic “turn towards things” opens the room for the construction of their social (auto) biographies, a development which already has been taking place in contemporary children’s literature. The problem of the creation of (auto)biographies of non-human subjects is presented in this article on the example of the picture book Otto: The Autobiography of a Teddy Bear by Tomi Ungerer. The artist gives the non-anthropomorphized plush toy the status of a non-human subject and an active actor of social life as a medium of unoffi cial memory of the Holocaust. Ungerer consciously and innovatively uses the key determinants of the posthuman discourse, including intimate childhood experiences.
