Mary (Green) Guzzwell (1909-1994), Newfoundland nurse, was born in 1909 in Winterton, Trinity Bay, Newfoundland. She received her nurse's training at Highland View Hospital, Amherst, Nova Scotia, graduating in 1932. From 1932 to 1939, Green was a district nurse in St. John's and in various outports. During the summers of 1936 and 1938, she was a nurse on the S.S. Kyle on its annual Labrador runs. Green was the first nurse to hold this position, which was more often held by American medical students. These experiences are chronicled in an article, "SS Kyle Nurse," in Them Days (v. 13, 1987).
In 1939, Nurse Green arrived in Bonne Bay as the first nurse in the new hospital. From 1943 to 1947, she held the position of Director of Public Health Nursing Service under the Newfoundland Commission of Government (1934-1949). Her annual reports, some illustrated with her own photographs, chronicle the experiences of rural and urban public health nurses. As a result of her services at this time, Green was made a M.B.E. on 5 November 1947.
Green was married in 1947 to Harold Guzzwell, a Newfoundland Ranger originally from St. John's. The couple had no children.
Nurse (Green) Guzzwell's record of registration with the Association of Registered Nurses of Newfoundland and Labrador (ARNN) indicates that she remained active in the nursing profession after 1947. While details of her career are sketchy, family members have indicated that she worked with the cottage hospital in Brookfield, Bonavista Bay, and in the Bowater's clinic in Deer Lake. From 1968 to 1974, she was the assistant evening supervisor at the Hoyles Home in St. John's. She retired in 1974 but maintained her ARNN registration until 1985. She died in St. John's on 20 March 1994.
