Brian Antonson was born and raised in British Columbia. He is associate dean of Broadcast and Media Communications at the British Columbia Institute of Technology.

In his early 20s, Brian collaborated with Rick Antonson and Mary Trainer to write and publish In Search of a Legend: Slumach's Gold in 1972. The incentive to create the book actually originated two years earlier as a way to celebrate the centennial of B.C.'s entry into Confederation in 1971. Inspired by the afterglow of Canada's centennial and Expo 67, the trio was part of a new generation that was passionate about being Canadian—and about all things Canadian. The trio created a publishing house, Nunaga (the Inuit word for "my land, my country") Publishing, and between 1972 and 1979 they published more than 25 books under this imprint and Antonson Publishing.
