This thesis addresses critically the work of American artist Allan Kaprow (1927-2006), focusing especially on the tensions Kaprow proposed between 'art' and 'life'. It presents a reconsideration of the most fertile period in Kaprow's career, from his undergraduate studies in the late 1940s to his mature work of the 1970s, prior to the increasing demands made on him to produce re-enactments of his early work. The period 1948-1976 presents a fuller overview of the themes and motivations of his practice than has been scrutinised in the existing literature. The research is based on extensive examination of the Allan Kaprow Papers at the Getty Institute, Los Angeles, which revealed significant and previously unstudied documentation and images. This archive and Kaprow's personal library in Encinitas, California have provided substantial previously unpublished evidence of his early interest in the American pragmatist John Dewey, and reveal many of the motivations for Kaprow's emphasis on change, together with his relational approach to form, context and process. The role of composer John Cage in the development of Kaprow's thoughts on chance helps elucidate the complexities inherent in the development of Kaprow's negotiation between chance and control. The present study also gives, for the first time, a comparative and detailed reading of the five drafts of Kaprow's Assemblage, Environments and Happenings (1966), a reading which sheds fresh light on his art and publications of the period. The thesis also presents a thorough reconsideration of the significance of play in Kaprow's work of the late 1960s and 1970s, including the tensions between and among play, work, hierarchy and liberation. Kaprow's many struggles to conceptualise and reconcile these tensions, and others, such as between audience and participant, private and public and narrative and history, were a necessary feature of the categories of art and artistic identity, including 'Happening', 'Activity' and 'Un-artist' that he helped bring into being.

In den vergangenen Jahren widmete sich eine stetig steigende Anzahl von Ausstellungen und Reenactments der Vergegenwärtigung und Re-Vision der Geschichte von Performance-Kunst und integrierte Aufführungen in diesen Kontext. Sie sind beweglicher Umgang mit den Performance-Archiven. Sie aktualisieren die Frage nach dem Charakter der Artefakte, auf die sich alte und neue Erzählungen zu und über Geschichte(n) der Performance beziehen und thematisieren ihre Lesbarkeit in je neuen Zusammenhängen. Wie in der Bewegungsspur, die den Zuschauern angeboten wird, Zugänge eröffnet werden, wird anhand von Ausstellungsbeispielen untersucht.

À l’orée des années soixante, la performance a cherché à imposer un art de l’action éphémère que n’entraverait aucun type de médiation, qu’il soit symbolique (la distance acteur/spectateur), technique (les médias), ou même linguistique (le langage, les signes). Enjeu de nombreux débats entre les années 1960 et 1990, ces tentatives ont trouvé de multiples formulations théoriques s’appuyant sur les outils du poststructuralisme en particulier, mais aussi sur des cadres de pensée différents, directement hérités du modernisme de Greenberg. On explore ici les étapes et enjeux de ce croisement, jusqu’à la rupture apportée dans les années 1990 et 2000 où les débats théoriques, toujours dirigés par des schémas poststructuralistes, redonnèrent une place centrale aux médiations, tout particulièrement au document. Or, la figure importante de la pratique artistique qu’est devenu le document depuis les années soixante s’avère mettre en question l’ontologie traditionnelle de la performance, orientée sur l’événement, autant que son épistémologie, qui valorise l’expérience directe. La prise en compte des dimensions instrumentales et artistiques du document nous conduit à réviser la poïétique traditionnelle de la performance et les théories de la communication qui lui sont liées, et à repenser par là même l’opposition entre objet et événement qui fonde la définition de la performance. C’est ainsi qu’on interroge le rapport de celle-ci à l’inscription, pour la redéfinir comme un art irréductible à son contexte d’exécution et travaillé en profondeur par la reproduction et la représentation, au travers notamment de l’étude de certaines figures exemplaires, Allan Kaprow, Chris Burden ou Tino Sehgal. / On the edge of the 1960’s, performance looked after imposing an art of ephemeral action that no kind of mediation would impede, be it symbolic (the distance between actor and spectator), technical (the medias), or even linguistical (language, signs). Those attempts led to numerous discussions between the 1960’s and the 1990’s, and have found numerous theoretical formulations using particularly the tools of poststructuralism, but also frames of thought directly inherited from Greenberg modernism. We explore here the stages and issues of this cross-over until the break of the 1990’s and 2000’s where the theoretical debates, always using poststructuralist schemes, gave a central role to mediations, particularly to the document. Documents have become an important figure of artistic practice since the 1960’s and turned out to question the traditional ontology of performance, based on the event, as well as its epistemology that promotes live experience. We try to consider the instrumental and artistic dimensions of the document ; this leads us to revise the traditional poetics of performance and theories of communication that are related to it, and to consider anew the opposition between object and event on which the definition of performance is based. Thus, we question the links between performance and inscription, redefined as an art that is irreducible to its context of execution and worked in depth by reproduction and representation, through the study of certain figureheads : Allan Kaprow, Chris Burden or Tino Sehgal.
