Born in 1951 in Trier, Germany, he collaborated in the 1970s with the artist Joseph Beuys(1921-1986), who was a key influence on his concept of photography, and thereafter with the French writer and photographer Hervé Guibert (1955–91).
To he Buddhist monks of Luang Prabang, for example, he presented, again and again, the resulting photographs and put their critique, their opinion and attitude at the basis of ongoing work.
On the island of Elba (Italy), he created a Botanical Garden, the “Orto dei Semplici Elbano” for the study and conservation of rare and endemic plants of the Tuscan Arcipelago.
It is situated next to an ancient Franciscan Hermitage, the “Eremo di Santa Caterina” that Berger discovered in 1977 as a ruin, and that has since become a creative meeting place for artists, writers and scientists, initiating various projects of literature, contemporary music, archaeology and botany.
Photography that is born out of the intimate dialogue with the Self and with what is loved, and that over the course of half a century has succeeded in extending itself to a cosmopolitan and universal dimension, carrying out an extraordinary, even unique journey within this great contemporary art."
