Defying Victorian ideas about womanhood, Fanny Bullock Workman (1859-1925) tucked her frizzy hair under a helmet and started climbing. This American trailblazer was instrumental in breaking the British stranglehold on Himalayan mountaineering and climbed more peaks than any of her peers, becoming the first woman to map the far reaches of the Himalayas. Cathryn Prince brings Fanny Bullock Workman to life, revealing how she navigated the male-dominated world of alpine clubs and adventure societies as nimbly as she climbed the deep crevasses and icy granite walls of mountains worldwide.
