About Mary Steinhauser

Lived 1942 – 1975 (aged 32). Mary Steinhauser was a Canadian social worker, peace officer and psychiatric and mental health nursing.

Mary Steinhauser (August 25, 1942 – June 11, 1975) was a Canadian social worker and prison classification officer who was killed during a hostage-taking at the British Columbia Penitentiary in 1975. On June 9, 1975, Steinhauser was one of fifteen people that were taken hostage by three inmatesAndy Bruce, Dwight Lucas and Claire Wilsonwho were attempting a prison breakout. Prior to the hostage-taking and her death, Steinhauser was an outspoken advocate against solitary confinement.

Personal life 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. Steinhauser, who was taken captive at knifepoint, volunteered to be the principal hostage, which meant that she was held in a room outside the vault area where the other hostages were kept. They also demanded safe passage out of the country.

The hostage stand-off lasted for forty-one hours. At approximately 1 A.M. on June 11, one of the hostages tried to overpower the inmates in an attempt to escape, after which point all of the hostages except Steinhauser retreated to the vault, where they locked themselves inside. Soon after, a tactical squad of prison officers attempted to rescue the hostages and fired upon the hostage-takers. Steinhauser, who was being held as a human shield in front of Bruce, was fatally shot in the process. It was also alleged that Hollinger had deliberately switched up the tactical team's guns in an attempt to keep from being identified as the shooter while claiming that he was collecting the guns in order to keep them away from prisoners.

In January 1976, Bruce appeared in a New Westminster provincial court, where he gave his account of the hostage-taking to Judge Philip Govan. The jury further recommended that future, similar incidents be handled by outside teams that have been trained in hostage situations. The incident was fictionalized in Christian Bruyère's play Walls and its film adaptation Walls. The Steinhauer role in those works was given the name Joan Tremblay, and was played by Andrée Pelletier in the film. In 2014 a stage performance entitled Brave: The Mary Steinhauser Legacy was held at the Terry Fox Theatre in Port Coquitlam.
