Alexander Philip (Pi) John Kennedy was born in Fort Smith on December 9, 1926, the first son of Philip Kennedy and Leoni Mercredi. In 1932 his mother died of tuberculosis at the age of 23. Pi went to residential school in Fort Resolution for two years, but his father took him out in 1934 to help trap. In 1936 his father built a cabin near Nataway Lake. Around that time, at the age of ten, Pi started driving a dog team, which would start a lifelong dedication to mushing. In 1944 Pi's father died of tuberculosis.
Throughout his life Pi generally trapped through the winter and spring on his trapline (sometimes partnering with someone else for the spring hunt) and got various seasonal summer work around Fort Smith. This included jobs such as crushing rock, digging and setting power poles, putting in the Fort Smith water system, working for Forestry, or in construction. In years where the trapping was good he did not need to take summer work.
Pi started taking photographs in earnest in the 1960s, and he also documented his life on Super8 film. Not only did he document aspects of life as a trapper and dog musher, but he also documented the community of Fort Smith, parades, fastball tournaments, special events and his extended family. His keen interest in radio, baseball, animals and dog mushing is documented as well. Pi notably trapped exclusively with a dog team until 1986. Even after buying a snow machine he continued to use dogs in the bush.
In 2010 at the age of 84, Pi suffered a stroke out on the trapline. After this, he moved himself and his dogs to Fort Smith permanently. Multiple books have been published about his life, including a series of children’s books in Cree published by the Northwest Territory Métis Nation in the 2000s, and a biography published with Patti-Kay Hamilton in 2023, launched on his 97th birthday.
