Czech paradise(1954)

Joseph Vallot, geographer, naturalist and mountaineer born in 1854 in Lodève, was a visionary man, full of humor and whose curiosity was insatiable. He had spent some forty years of his life studying the Mont Blanc massif, sacrificing a good part of his fortune to this multifaceted passion.
