Leanne Betasamosake Simpson 1971 - present · Mississauga Nishnaabeg / Canada
Leanne Betasamosake Simpson is a Mississauga Nishnaabeg writer, scholar, musician, and activist. She is one of the most important contemporary indigenous thinkers in North America. She works on what is sometimes called indigenous resurgence: the recovery and renewal of indigenous languages, knowledge, and political life. She was born in 1971 in Canada. She belongs to Alderville First Nation, a Mississauga Nishnaabeg community in southern Ontario. The Mississauga Nishnaabeg are part of the larger Anishinaabe (also spelled Nishnaabeg) family of nations. The Anishinaabe are one of the largest indigenous peoples in North America. Their territory traditionally covered much of what is now the Great Lakes region of Canada and the United States. They have lived there for thousands of years. Simpson grew up between worlds. She is part of an Anishinaabe community. She also lived in non-indigenous Canadian society. She studied biology and resource management at university, earning her PhD in 1999. She was trained in Western academic methods. She was also learning her own people's language, ceremonies, and intellectual traditions. The combination shaped her work. She brings academic rigour to indigenous knowledge while also pushing back against academic frameworks that distort what they study. She has written or edited around a dozen books. She has produced several music albums. She co-founded the Dechinta Centre for Research and Learning in the Northwest Territories, an indigenous educational institution. She was a major voice during the Idle No More movement that began in 2012, a wave of indigenous political action across Canada. She is now in her fifties and remains one of the most active indigenous thinkers and artists in North America.
