"Sur Les Traces De Premier De Cordée", a color documentary from 1952 which will be released the same year as the eponymous photo book published by Arthaud, features Roger Frison-Roche and his sidekick Georges Tairraz II on the Aiguille du Grépon (3482 m) in the Aiguilles massif which overlooks the Chamonix valley. Together they co-produce the images of the ascent. The young Pierre Tairraz, who completed his training in Paris, at the school in the rue de Vaugirard (Cinema promotion in 1953), also took part in this very technical aerial filming as assistant to his father Georges Tairraz II and cameraman.
