In Memoriam – Professor Peter Stangeby (1943 – 2025)

Peter StangebyThe University of Toronto Institute of Aerospace Studies and the Division of Engineering Science are saddened to announce the passing of Professor Emeritus Peter Stangeby.

Born in Arvida, Quebec, Peter grew up in Brockville, Ontario. He first came to U of T as an undergraduate in the 1960s, completing his Master’s degree in 1967. He then went on to earn his PhD/DPhil in plasma physics at Oxford University, U.K. in 1972.

Professor Stangeby specialized in fusion energy research and was known internationally as an expert on the boundary plasma physics of magnetic confinement fusion reactors. In addition to his work at U of T, he also spent time as a research scientist in Oxford, U.K. and in San Diego, U.S.A. Over the course of more than 50 years, he had a profound influence within his field, and was inducted as a Fellow of the Royal Society of Canada and of the American Physical Society.

In addition to his talents as a researcher, Professor Stangeby will be remembered for his ability to connect with his students, fostering multiple generations of engineering expertise. For many years, he taught first-year courses in calculus and physics to undergraduate students in the Engineering Science program. Students said his lectures were memorable and fun, and that he often included important life lessons alongside the fundamental scientific and mathematical principles he taught. They appreciated how he was always readily available to answer questions outside of class. He also supervised many graduate students who went on to life-fulfilling positions around the world.

Professor Stangeby’s passion for research and teaching was only exceeded by his love for his family. He is survived by Sharron, his wife and inseparable companion of 61 years, as well as his daughter Kim (Paul), his grandchildren Maddie, Lauren and Lucas and his sisters Beth and Valerie (David). He was preceded in death by his son Adam, his parents and his brother Rick.

Known for his quick wit and sense of humour, Professor Stangeby was also a talented pianist and loved music, live theatre, travel and reading, especially history.

He will be missed immensely by the entire U of T Community.
