Mourning the loss of emeritus faculty member Kenneth Kowalski
Kenneth L. Kowalski, a towering figure in the Department of Physics at Case Western Reserve University for over six decades, passed away in May at the age of 91. He played a significant role in the department being known as the highly-regarded institution for research and academia that it is today.
Kowalski joined CWRU in 1963, drawn by the university’s burgeoning reputation in nuclear and particle theory. His early work delved into collision theory, nuclear physics and high-energy domains. His research on the effects of protons and deuterons colliding laid the groundwork for future explorations in the field. Over the years, he collaborated with colleagues and post-docs to develop innovative techniques for analyzing these complex interactions.
Cyrus Taylor, a professor of physics and colleague, highlighted Kowalski’s enduring influence.
“His publications spanned decades, covering supersonic flow, relativistic collision theory, quantum field theory and high-energy particle physics,” Taylor said. ”Ken’s work in radiation amplitude zeros was pivotal, laying the foundation for modern amplitude symmetries in quantum field theory.”
Kowalski, who earned his doctorate from Brown University, was also highly regarded for his work as chair for the department. Professor of Physics and Distinguished University Professor, Bob Brown, shared fond memories of working alongside Kowalski for over 40 years.
“Ken was not only a great physicist but also an inspiring leader. His support for faculty as department chair was invaluable,” Brown said. “He secured funding for postdoctorates, fostering critical collaborations that advanced our research and secured long-term National Science Foundation support.”
In the classroom, Kowalski’s teaching legacy was equally impressive. Taylor recalled how Kowalski once shared a 13-page list of courses he taught at CWRU, which are still remembered by former students for their rigor and high standards.
Brown recalled, “Ken had an extraordinary ability to transition from theoretical realms to the practical challenges of experimental physics. His agility and grace in both spheres were a testament to his abilities as a physicist and his character as a human being.”
Kenneth L. Kowalski’s contributions and his dedication to teaching have left an indelible mark on those that worked alongside him, students who followed in his path, and the entire field of physics.
