In Memoriam

UBC Mathematics honours the memory of our former faculty members

Colin Clark (1931-2024)


Colin earned his B.A. at UBC and completed his Ph. D. at the University of Washington in 1958. In 1960 he joined the Math Department at UBC, where he began his research publishing papers on partial differential equations, functional analysis, and spectral theory. Colin founded several entirely new areas of mathematical-biology research starting with Bioeconomics in 1971, followed by Behavioural Ecology in 1983. Colin collaborated with biologists and economists at UBC and elsewhere, and worked with provincial, federal, and international resource management institutions. His book, Mathematical Bioeconomics: the Optimal Management of Renewable Resources (3rd edition 2010) is a classic in fisheries economics and a foundational text for students, scientists, and resource managers. Colin was the founder of Mathematical Biology at UBC and was considered one of the most influential bioeconomists of his generation.

In 1997 Colin was elected Fellow of the Royal Society for his contributions to the conceptual foundations of biological resource management and behavioural ecology. Colin was also named a Fellow of the International Institute of Fisheries Economics & Trade (IIFET) in 2016.

Colin W. Clark will be remembered not only for his intellect and profound scientific impact but also for his warmth, humour, and unwavering love for his family. His legacy lives on in the hearts of all who had the privilege of knowing him.

Brauer, Fred (1932-2021)

Professor Fred Brauer

Fred Brauer graduated from the University of Toronto in 1952, and completed his PhD at MIT in 1956. He was a professor of Mathematics at the  University of Wisconsin, Madison, from 1960 to 1996, where he also served as department Head. After retirement, Prof. Brauer started a new career as an honorary professor in Mathematics at the University of British Columbia, where he became an active member of the Mathematical Biology group until his death in 2021.

Fred was a pioneer in mathematical epidemiology, continuing to carry out an active program of research and to publish papers until his recent illness. Fred trained numerous students, mentored young scientists, contributed to organization of workshops, and wrote ten books.  Prof. Brauer's most recent book, published in 2019 with two coauthors is Mathematical Models in Epidemiology (Springer).

Fred is greatly missed by many of us who enjoyed his wisdom and breadth of knowledge, as well as his special sense of humour, his kindness, and his friendship.

Edmond Granirer (1935-2020)

Edmond Granirer


Eddie was born in Romania, emigrated to Israel in 1950 and received his Ph.D. at Hebrew University in 1962 under Harry Kesten. His thesis treated the measure theoretic properties of amenable semigroups, an area he returned to many times in his long research career. He was active in research until his death. In fact, his last paper was published after he died.  A member of the Royal Society of Canada, Eddie's main area was the general theory of locally compact groups. He was known for his warm, ironic sense of humour, which was inherited by his son David, a well known stand up comedian and author.


Schoetzau, Dominik (1970-2020)

Professor Dominik Schoetzau

Dominik obtained his PhD from ETH Zurich, working under the supervision of Christoph Schwab. After completing a postdoctoral fellowship in Minnesota, he joined the Department of Mathematics at UBC in 2003. The main area of his expertise was numerical methods for partial differential equations, and in particular, finite element methods. He was a world-renowned expert in discontinuous Galerkin (DG) methods, and made significant contributions that turned those techniques into a powerful and broadly used family of methods. Dominik published several influential papers on error and convergence of DG methods, providing rigorous analysis for establishing their utility. He also made significant contributions on the efficient numerical solution of finite element discretizations of Maxwells equations and incompressible magnetohydrodynamics problems. Despite his health struggles, Dominik continued to produce impactful mathematical results in the last several years. One of his last research projects produced a sequence papers proving exponential convergence of hp-FEM for elliptic problems in polyhedral domains.

Dominik was a warm person, husband and father. A brilliant mathematician, his outstanding contributions in the field of numerical analysis will be long lasting.

Donald Ludwig (1933-2018)


Professor Emeritus, Donald Alfred Ludwig's academic achievements are remarkable. Don skipped full 3 years of school as a young man, after high school he received a Bachelor of Arts in Music, as well as a MS and PhD in Mathematics from New York University. He authored many publications from 1960-2005. Don was an instructor at Princeton University, Associate Professor and Professor of Mathematics at NYU, Professor of Mathematics and Zoology at UBC. Professor Emeritus of Mathematics and Zoology at UBC. He was honored by a Guggenheim Fellowship in 1970, was a fellow of the Royal Society of Canada, and fellow of AAS, Foreign member of American Academy of Arts and Science.

Don was a scholar, musician, an accomplished mathematician and professor. He was a skilled outdoorsman, husband, father, grandfather and great grandfather. He loved reading and spending time with numerous family members. Don has many relatives in the eastern US and friends around the world.
