It is with deep sadness that we announce the passing of William 'Bill' Morton, who died in May 2024 at the age of 73.

Bill was a beloved member of the academic community, known for his sharp intellect, generous spirit, and unwavering positivity.

Born in 1951, Bill’s academic journey began at the University of Edinburgh, where he studied Mathematical Physics. His passion for mathematics led him to Cambridge, where he pursued Part III Mathematics, laying the foundation for a remarkable career in both theoretical and applied sciences. He was awarded the Mayhew Prize in 1974, alongside Bernard Silverman, by the Faculty of Mathematics, University of Cambridge. The prize is awarded to the student(s) showing the greatest distinction in applied mathematics.

Bill went on to join the Department of Chemical Engineering and Biotechnology (CEB) in 1978/9, where he made lasting contributions as a junior lecturer for 10 years. Transitioning from his early research on quarks at the Department of Applied Mathematics and Theoretical Physics (DAMTP) under the guidance of John Polkinghorne, Bill found his true calling in Chemical Engineering.

As a junior lecturer, he quickly gained recognition for his mastery of both the theoretical and practical dimensions of the field. His work spanned diverse areas, including combustion dynamics, computerised flow-sheeting, radiative heat transfer, and chaotic phenomena in heterogeneous catalysis.

Beyond his scholarly contributions, Bill was a cherished mentor who guided numerous research students with patience and insight. His office on Pembroke Street became a haven of knowledge, where students and colleagues alike found inspiration and support. Bill’s ability to combine rigorous scholarship with genuine warmth and humility made him a treasured member of the department.

In 1989, Bill moved to Canada, where he continued to share his expertise with SACDA in London, Ontario. Later, he returned to Edinburgh, where he took on a Lectureship that brought him great joy and fulfilment.

Bill was a true gentleman, whose kindness and cheerful demeanour left a lasting impression on all who knew him. He embodied the ethos of inclusivity and excellence, enriching the field of Chemical Engineering with his diverse insights and dedication.

William 'Bill' Morton leaves behind a legacy of intellectual brilliance and heartfelt warmth. His loss is deeply felt by all who had the privilege of knowing him.

His memory will be cherished by colleagues, students, and friends alike.
