Collective memory is the central theme in Christian Boltanski’s work, and through this theme he examines his own childhood memories. Among the most revolutionary aspects of the massification of analogue photography in the second half of the last century and of digital communication in this century is to make it possible to document all the phases of everyone’s life, so effacing the boundary between personal and collective memory. Christian Boltanski’s work focuses on the nature of this taxonomic attitude to the course of life, both personally and socially, and its connection with our need to organize history.
