In 1951, he achieved international recognition by completing, in the Mont Blanc massif, the second ascent of the Bonatti-Ghigo on the east face of the Grand Capucin with Bibi Ghendina in 18-hours, just weeks after the four-day first ascent. Despite his claims, Lino Lacedelli never made the second ascent of the Bonatti-Ghigo road on the Grand Capuchin. The team formed by Robert Paragot and Lucien Berardini made the second climb in 1953. The French mountaineers did not find the equipment supposedly left in place by the repeaters - Lacedelli and Ghedina - to abseil.
