Jackson Beardy, PNIAI, was an Anishinaabe (Oji-Cree) painter and graphic artist born on the Garden Hill First Nation at Island Lake, Manitoba. He was raised by his maternal grandparents and spent his early childhood speaking solely the Oji-Cree language and learning community oral histories. At seven years old, he was removed from his family to attend the Brandon Indian Residential School in southwestern Manitoba, later continuing his secondary education in the public school system in Portage la Prairie. Following high school, Beardy pursued formal studies in commercial art and graphic design at the Technical Vocational High School in Winnipeg.

During the late 1960s, Beardy transitioned from commercial drafting to fine art, drawing upon the oral histories, sacred narratives, and animal iconography of the northern woodlands. His distinctive visual vocabulary featured precise contour lines, stylized figurative arrangements, and selective palettes applied to paper, canvas, and birchbark. By 1970, his growing reputation led to regional and national projects, including artistic contributions to the Manitoba Centennial celebrations and early museum acquisitions by public institutions across Western Canada.

In 1973, Beardy joined Daphne Odjig, Alex Janvier, Norval Morrisseau, Carl Ray, Joseph Sanchez, and Eddy Cobiness to co-found the Professional Native Indian Artists Inc. (PNIAI) in Winnipeg. Informally referred to as the Indian Group of Seven, this collective was established to advocate for self-determination, professional recognition, and systemic inclusion within major Canadian public institutions. As a founding director, Beardy was instrumental in organizing collective strategies, participating in collaborative meetings, and promoting Indigenous modernism across Canada and abroad.

Throughout the mid to late 1970s, Beardy dedicated substantial time to cultural and educational leadership. He held consultative roles with regional and national organizations, including service with the Department of Indian Affairs and Northern Development as an art advisor. During this period, he also taught Indigenous art and cultural studies at Brandon University and the University of Manitoba. In 1982, he accepted an appointment as senior arts and culture advisor to the Assembly of First Nations in Ottawa, where he worked on cultural heritage policy and repatriation strategies until his health declined.

Beardy died in Winnipeg on December 7, 1984, at the age of forty. Following his death, his career and contributions to Canadian art history have been recognized through major public museum retrospectives and inclusion in permanent collections nationwide. His artworks are preserved in public institutions, including the National Gallery of Canada in Ottawa, the Winnipeg Art Gallery, the Canadian Museum of History in Gatineau, the McMichael Canadian Art Collection in Kleinburg, and the Royal Ontario Museum in Toronto.
