Bernard Vaucher, nicknamed "Barney" and born in 1950 in Marseille, discovered mountaineering at the age of fifteen. At the beginning of the 1970s, he was one of the best climbers in Provence, alternating firsts in various massifs (Bavella, Dévoluy, Dolomites, Hoggar, Karakorum, Verdon and of course Calanques), with long-pitch routes in Yosemite, in the Dolomites or the Mont-Blanc massif. At the turn of the millennium, he developed a taste for writing. We owe him a work on the history of climbing in the Calanques, Des Rochers Et Des Hommes, as well as another co-written with his wife, dealing with their protection; he is also the author of a detective novel, Meurtre Au Verdon. A man of sharing, to the pleasures of the mountains and climbing, he adds that of writing and transmitting his passion and his knowledge. We owe him reference works on climbing in the Calanques, in Corsica and in the Verdon.
