Donald Glenn Ivey (1922–2018) was a transformative figure in 20th-century physics, though his primary laboratory was not a basement cleanroom, but rather the television screen and the undergraduate lecture hall. A professor at the University of Toronto for decades, Ivey—alongside his longtime collaborator Patterson Hume—revolutionized science communication and physics pedagogy, bringing the rigors of classical mechanics to millions of viewers with wit, clarity, and a touch of theatrical flair.
1. Biography: From Winnipeg to the Principal’s Office
Donald Ivey was born on March 22, 1922, in Winnipeg, Manitoba. He moved east to attend the University of Toronto (U of T), where he would spend nearly his entire professional life. He earned his B.A. in 1944, followed by an M.A. in 1946, and a Ph.D. in 1949. His early research focused on the properties of polymers and the absorption of ultrasonic waves in liquids, but he quickly found his true calling in the transmission of knowledge rather than the discovery of new particles.
Ivey joined the faculty of the Department of Physics at U of T in 1949. His career trajectory was marked by a rare combination of administrative leadership and public outreach. In 1963, he was appointed the founding Principal of New College at the University of Toronto, a position he held until 1974. Under his leadership, New College developed its unique identity as a multi-disciplinary hub within the university. Even after retiring from administrative duties, he remained a Professor Emeritus, continuing to influence the university's direction until his death on June 18, 2018, at the age of 96.
2. Major Contributions: Humanizing the Laws of Nature
Ivey’s greatest contribution was the development of a new methodology for teaching physics. In the late 1950s and early 1960s—the "Sputnik era"—there was an urgent global push to improve science education. Ivey and his colleague, J.N. Patterson Hume, recognized that physics was often taught as a dry collection of formulas. They sought to change this by focusing on the conceptual beauty and the "common sense" (or lack thereof) in physical laws.
The Hume and Ivey Duo:
The pair became a Canadian institution. They adopted a "straight man and funny man" dynamic that made complex topics accessible. They were pioneers in using film and television as serious pedagogical tools, moving beyond simple demonstrations to create visual metaphors for abstract concepts like relativity and frames of reference.
The Nature of Things:
In 1960, Ivey and Hume became the original hosts and creators of the CBC television series The Nature of Things. While the show is now synonymous with David Suzuki, it was Ivey and Hume who established its foundation as a platform for high-level scientific inquiry presented for a general audience.
3. Notable Publications and Films
Ivey’s "publications" were often cinematic as much as they were printed. His work in the Physical Science Study Committee (PSSC) in the United States remains legendary in physics education.
- Frames of Reference (1960): This educational film is considered a masterpiece of science communication. In it, Ivey and Hume use a rotating table and a falling ball to demonstrate how motion looks different depending on the observer's perspective. It is still screened in university physics departments today for its perfect clarity.
- Physics (Volumes 1 & 2) (1974): Co-authored with Patterson Hume, this textbook became a staple for introductory physics. It was noted for its conversational tone and its emphasis on the "why" behind the "how."
- Physics: A Television Course: A series of 30-minute programs produced for the CBC and later distributed globally, which served as a precursor to the modern "Massive Open Online Course" (MOOC).
4. Awards & Recognition
Ivey’s contributions to education and public service were recognized with some of Canada’s highest honors:
- Officer of the Order of Canada (1982): Awarded for his contributions to science education and his role in the founding of New College.
- The Sandford Fleming Medal (1982): Awarded by the Royal Canadian Institute for outstanding contributions to the public understanding of science.
- The Medal for Outstanding Achievement in Industrial and Applied Physics: Awarded by the Canadian Association of Physicists (CAP).
- The Royal Society of Canada's McNeil Medal (1992): Shared with Patterson Hume, recognizing their lifelong dedication to science communication.
5. Impact & Legacy
Ivey’s legacy is twofold: institutional and pedagogical. At the University of Toronto, the Ivey Library at New College stands as a testament to his role in shaping the college's intellectual life.
In the broader field of physics, he helped shift the focus of undergraduate education from rote memorization to conceptual mastery. His films, particularly Frames of Reference, influenced generations of physicists, including Nobel laureates who cite those black-and-white films as their first moment of true "seeing" in physics. He proved that rigorous science did not have to be humorless, and that the medium of television could be used for profound intellectual enrichment.
6. Collaborations
The most significant partnership of Ivey’s life was with J.N. Patterson Hume. Their collaboration lasted over 50 years. While Hume was an expert in the emerging field of computer science (helping to develop the first compilers), Ivey provided the structural framework for their physics presentations. They were often referred to as the "Laurel and Hardy of Physics," a title they embraced to lower the barrier of entry for intimidated students.
He also collaborated closely with Lister Sinclair, the legendary CBC producer, to bring The Nature of Things to life, ensuring that the scripts maintained scientific integrity while meeting the demands of broadcast television.
7. Lesser-Known Facts
- The "Upside Down" Intro: In the famous Frames of Reference film, Ivey begins the segment appearing to be upside down, only for the camera to rotate and reveal he was actually right-side up while the room was inverted. This was achieved without digital effects, using a custom-built rotating set—a precursor to the techniques later used by Stanley Kubrick in 2001: A Space Odyssey.
- A Passion for Theatre: Ivey was an avid fan of the performing arts. This theatricality informed his teaching style; he viewed the lecture podium as a stage and the students as an audience that needed to be engaged, not just lectured at.
- The "Ivey-Hume" Award: To this day, the University of Toronto presents the Ivey-Hume Award to students who demonstrate excellence in both physics and the communication of science, ensuring his philosophy of "clarity through engagement" continues.
Donald Ivey’s career serves as a reminder that the advancement of science is not only about the discovery of new facts but about the effective transmission of those facts to the next generation. He was a scholar who believed that if a concept couldn't be explained simply, it wasn't truly understood.
