Chantal Mauduit (24 March 1964 – 11 May 1998) was a French alpinist. Born in Paris, she arrived in the French Alps at age five and started climbing at the age of 15. After several difficult routes in the Alps, she focused her attention on the Andes, and then the Himalayas, where she climbed K2 (1992; fourth woman overall, and solo climb), Shisha Pangma (1993), Cho Oyu (1993), Lhotse (1996; first woman solo), Manaslu (1996), and Gasherbrum II (1997), all without supplemental oxygen. Along with her Sherpa partner Ang Tsering, she was killed by an avalanche on Dhaulagiri on May 11, 1998 while asleep in their tent. In honor of her generosity, her friends and family created a foundation to help needy Nepalese children, especially with schooling: The Association Chantal Mauduit Namasté.
Mauduit needed to be rescued by Ed Viesturs and Scott Fischer on descent from K2 in 1992, Viesturs and Fischer gave up their own summit attempt of K2 at the time in order to get Mauduit, who had become snow blind, to safety. According to Viesturs, Mauduit never thanked them for the rescue. Once again after collapsing during a failed summit attempt on Mount Everest in 1995 Mauduit was carried off the mountain by the good graces of other climbers. Some climbers perceived her as ungrateful for never acknowledging the lifesaving assistance that she had been given. She was also accused of not pulling her weight on climbing expeditions, leaving it to others to fix ropes on difficult sections of mountain or stock higher camps with food and other provisions, and then taking advantage of their work.
Mountaineer Ed Viesturs also raised questions about the cause of Mauduit's death, suggesting either suffocation or carbon monoxide poisoning as other possible causes. Viesturs was on Dhaulagiri at the time of Mauduit's death, but had no first hand knowledge about how Mauduit died. The French autopsy concluded that the cause of death was a broken neck as a result of an ice or rock strike, and Viesturs does not formally question the autopsy's findings. Frederique Delrieu, a climbing companion of both Viesturs and Mauduit, saw Mauduit's body first-hand and confirmed that she had a broken neck.
