La trilogie du Bonheur is the first book by the artist Marvin Bonheur and brings together ten years of photographs taken in the Seine-Saint-Denis department where he grew up. His gaze, sometimes tender, nostalgic or critical, bears witness to his experience in this singular territory. Marvin Bonheur grew up in places often labelled “no-go zones”, where hope is scarce and the atmosphere heavy. With his friends he hangs around, he plays, but very early on he feels the negative waves linked to his identity and his origins. The series divides into three parts, and the book is structured accordingly. “Alzheimer”, the first, dives into his memories, capturing strong moments of his childhood and adolescence up to his departure at the age of twenty-one. The photographs are taken like snapshots of his memory, seeking to preserve and document the past. The second chapter, “Thérapie”, explores the daily reality of today's youth, denouncing injustices and demystifying the stereotypes of a culture often rejected by society. Bonheur moves closer to individuals, makes portraits, and becomes aware of his attachment to “the forgotten”. “Renaissance”, the final chapter, concludes the photographer's quest for identity, evolving between the place that shaped him and the new perspectives he explores.
