Mary Steinhauser was born in
Duncan,
British Columbia, on August 25, 1942, to August Steinhauser and Johanna Reisner. She was the eldest daughter of two children. Her father emigrated to Canada in 1925 from
Ravensburg,
Germany, and made a living as a farmer in
Edmonton,
Alberta, and subsequently moved to
Lake Cowichan, British Columia, where he worked in the sawmill. Her mother immigrated to Canada in 1939 from
Vienna. Steinhauser's parents married in 1941. Steinhauser grew up in Lake Cowichan until she was five years old, when she moved with her family to the town
Burton, in the
West Kootenays, where her parents had purchased a farm. Upon graduation from secondary school in
Nakusp, she began her training as a psychiatric nurse at
Essondale. After working at Essondale for two years, Steinhauser moved to
Toronto and worked as a nurse at the
Queen Street Mental Health Hospital for one year. Following this employment, she returned to British Columbia and took up nursing duties at Tranquille School for the mentally handicapped in
Kamloops, holding this job for two years. Steinhauser eventually began work as a psychiatric nurse for the
Matsqui Institution, a newly opened
medium security prison in
Matsqui. From 1967 to 1970 she studied psychology and sociology at
Simon Fraser University, where she graduated in 1971 with a BA (Honours) in Psychology and Sociology. Immediately after attaining her degree, she began graduate studies at the
University of British Columbia in social work; Mary was awarded her Master of Social Work degree in May 1973. ==Hostage-taking incident==
