## History

Mount Jimmy Simpson is named for **Jimmy Simpson** (1877–1972) who was a respected [outfitter](/source/Outfitter) in the early explorations of the Canadian Rockies.[1] Jimmy worked as a cook for [Tom Wilson](/source/Thomas_Edmonds_Wilson) and learned the guide and outfitting business from [Bill Peyto](/source/Bill_Peyto). In 1902, while working for Peyto, he was given the responsibility of leading [James Outram's](/source/James_Outram_(mountaineer)) climbing expedition into the headwaters of the [North Saskatchewan River](/source/North_Saskatchewan_River) and [Columbia Icefield](/source/Columbia_Icefield).[3] Jimmy built a small log cabin for use with his outfitting business on the north shore of Bow Lake. It was expanded in 1937, and is now the historic *Num-Ti-Jah Lodge*. Jimmy continued actively guiding until the end of World War II when his son, Jimmy Simpson Junior, took over the business.[1]

The [first ascent](/source/First_ascent) of Mount Jimmy Simpson was made in 1897 by [J. Norman Collie](/source/J._Norman_Collie), George Percival, and [Peter Sarbach](/source/Peter_Sarbach).[3] The mountain's name was officially adopted in 1973 by the [Geographical Names Board of Canada](/source/Geographical_Names_Board_of_Canada).[2]
