Sigurd Ferdinand Olson was an American writer, environmentalist, and advocate for the protection of wilderness. For more than thirty years, he served as a wilderness guide in the lakes and forests of the Quetico-Superior country of northern Minnesota and western Ontario. He was known honorifically as the Bourgeois — a term the voyageurs of old used of their trusted leaders.
