Dr. Maria Daria Haust, OC, MD, MD(hc), FRCPC (née Jaworska)

Peacefully at her residence in Toronto. She leaves behind her husband of 70 years, Dr. Heinz Haust; her sons, Bill and his wife Judy, and Jan and his wife Millie; grandsons, Andrew, Lee and his wife Deborah, Marco and Julius; and great-grandchildren Evers, Quinn and Mabel, to whom she was devoted. A native of Poland with a medical degree from the University of Heidelberg, Germany, Daria moved to Canada with her husband in 1952.

Over the years, she earned worldwide recognition as a pathologist, researcher and one of the pioneers of Paediatric Pathology as a separate discipline. Among her many national and international awards were the Gold Medal of the International Atherosclerosis Society, Distinguished Pathologist of the US/Canadian Society of Pathology, the Canada Council Killam Prize in Medicine, three honorary degrees and, in 2006, she was named an Officer of the Order of Canada. A devoted professor, she also treasured her Best Teacher awards. She was the first female professor in the Faculty of Medicine at Queen’s University (Kingston) before teaching for many years at Western University (London), where she subsequently remained active as Professor Emeritus. In fact, “retirement” was not in her vocabulary! Never losing ties with her beloved Queen’s, she became Professor to Adjunct Academic Staff in the Department of Pathology and Molecular Medicine up until her death.

Multi-lingual, she loved to quote Latin: Si tacuisses, philosophus manisses; Audiatur et altera pars; No scholae sed vitae discimus. The family is grateful to those who helped ease her final journey: her friend, Bruna Nota, her doctor, Peter Kopplin (Christie Gardens), Vasta (private caregiver), Aster (HCCSS), and the fine caregivers from Pearl Domestic Agency. According to her wishes, there will be no service. Her final resting place will be in the family plot in Marburg, Germany.

Daria Haust would be appreciated.
