Billing themselves as the 'World's Highest Couple', they successfully climbed Gasherbrum II (8,035 m/26,360 ft) in 1982 with Liliane's brother, Alain Bontemps, and Nanga Parbat (8,126 m/26,658 ft) in 1984 (first female ascent of this peak for Liliane). Although narrowly failing to make the summit of Makalu (8,462 m/27,765 ft), they nevertheless put the finances together to attempt K2 (8,611 m/28,268 ft) in 1986 with a small team consisting of themselves, Polish climber Wanda Rutkiewicz and French climber Michel Parmentier.
