Mary Gzowski – Art, Science, and Wit

Mary Gzowski (1910–1993) never followed a conventional path, but she embodied the intersection of art and science that defined medical illustration. Her family background made that blend almost inevitable: her maternal grandfather, Dr. Clarence Ronald Church of Ottawa, rooted her in medicine, while her father’s family was deeply engaged in the arts.

Educated at Miss Edgar’s and Miss Cramp’s School for girls in Montreal, Gzowski went on to study under Adam Sherriff Scott of the Beaver Hall Hill Group and even sat for exams at the Royal Academy School of Art in London. Beyond her studies, she was a lively and social figure—an active member of the Junior League, a dedicated fencer, and the first female member of the Arts Club of Montreal.

Her entry into medical art came, as she later said, “quite by accident.” While helping the Junior League run a hospital canteen, she drew a cartoon poster about rising sandwich prices. A doctor noticed and asked her to try some pathology drawings. “My first assignment was a pickled kidney,” she recalled. “When they served me a beef and kidney pie for lunch, and I ate it without a qualm, I knew I could handle the job.” That moment launched her career.

By 1938 she was working in the pathology department at the Montreal General Hospital, later reinforcing her skills with anatomy classes and autopsy reports at McGill. In 1955 she became the hospital’s official medical illustrator.

Known for her confidence, she was unafraid to correct physicians and often reminded them of past findings. She once reported cases of cerebral aneurysms in older patients—contradicting accepted medical belief—and her observations were duly incorporated into lectures.

Her illustrations were prized for their clarity and teaching value:

“Medical drawing can do what photographs can’t,” she explained. “They can remove the blood and gore and show what the doctor wants emphasized.”

She also brought humour and artistry into her work, painting murals around Montreal, joking with doctors, and slipping playful touches into hospital posters.

This mural is a fascinating anomally in the known work of Mary Gzwoski. It hints at an interest in surrealist principles, defined often by dreamlike, illogical and uncanny elements. The mural was originally located in the Montreal General Hospital and created for the April 1955 meeting of the Montreal Medico-Chirurgical Society. Now housed at the Maude Abbott Medical Museum, McGill University.

Painted in 1955, this mural was moved to a new location at the Montreal General Hospital in 1981.

When Eleanor Sweezey later joined the MGH, she found Gzowski’s illustrations still central to the art department. Recognizing their importance, Sweezey preserved many of them in the McGill University and MUHC Archives. In 1993, the Arts Club of Montreal honoured Gzowski as its first female member, cementing the legacy of a woman who brought wit, rigor, and artistry into medicine.
