Dorothy Pilley (1894–1986) was a trailblazing writer and mountaineer who led the way for women’s climbing and co-founded the Pinnacle Club for women in 1921. She climbed ridges and sheer faces around the world, creating a legacy that is admired to this day. In 1928, together with her husband I.A. Richards and Swiss Guides Joseph and Antoine Georges, she pioneered a route up the north-north-west ridge of the Dent Blanche in Switzerland. Climbing Days, a celebrated memoir of her early life and climbs was published in 1935.
