The John von Neumann Prize includes a $5,000 monetary prize and a certificate. A lecture is required and will be publicized in meeting announcements. SIAM will reimburse the recipient for reasonable travel expenses incurred in attending the award ceremony and giving the lecture.

The John von Neumann Prize will next be awarded at ICIAM 2023.

The prize is presented by the SIAM President at the Prizes and Awards Luncheon. The announcement of the award will appear in *SIAM News*, the SIAM website, and appropriate electronic media.

The fund was started with contributions from IBM Corporation and other organizations. It has been augmented by SIAM.

The 2023 John von Neumann prize is awarded to Yousef Saad for fundamental contributions to scientific computing, especially algorithms for sparse linear systems, eigenvalue problems, nonlinear equations, graph algorithms, and their applications to a wide range of problems in computational science and engineering including quantum chemistry, material science, and data science. His two outstanding monographs “Iterative Methods for Sparse Linear Systems” and “Numerical Methods for Large Eigenvalue Problems” have been highly influential on researchers and practitioners alike, and remain models of expository writing in these important areas of applied mathematics.

The 2022 John von Neumann Prize is awarded to Leah Edelstein-Keshet in recognition of her far-reaching contributions to mathematical biology. Her work on cellular biophysics as well as collective behavior of organisms has had enormous impact in deciphering biological processes. In addition, her book “Mathematical Models in Biology" is a classic that has been used by students worldwide and, in no small part, laid the foundation for interdisciplinary research in mathematics and life sciences that is flourishing today.

The 2021 John von Neumann Prize is awarded to Chi-Wang Shu for fundamental contributions to the numerical solution of partial differential equations. His work on finite difference essentially non-oscillatory (ENO) methods, weighted ENO (WENO) methods, finite element discontinuous Galerkin methods, and spectral methods has had a major impact on scientific computing.

The 2020 SIAM John von Neumann Prize is awarded to Lloyd Nicholas Trefethen for his ground-breaking contributions across many areas of numerical analysis, which include his own notion of pseudospectra of non-normal operators, the Chebfun system for numerical computing with functions, and his seminal contributions to numerical approximation. He is an outstanding expositor of applied mathematics and his books are beautifully written, widely accessible, and highly original.

The 2019 John von Neumann Prize Lecture is awarded to Margaret H. Wright in recognition of her pioneering contributions to the numerical solution of optimization problems and to the exposition of the subject. Her research has deeply impacted the theory and practice of optimization. Her 1981 book “Practical Optimization” (with Philip E. Gill and Walter Murray) is one of the most influential books on the subject. Through her many leadership roles, she has inspired and encouraged countless others.

The 2018 John von Neumann Lecture Prize is awarded to Charles F. Van Loan in recognition of his pioneering contributions to research in numerical linear algebra and to the exposition of the subject. From generalized singular value problems and structured eigenvalue problems to matrix functions, and most recently in tensor computations, he has led the way in developing theory and algorithms – with a particular view to applications in signal processing and control theory. Van Loan is a brilliant communicator, in any medium, for any audience. His book *Matrix Computations*, now in its fourth edition, is the canonical reference and has shaped the field and influenced the way we think about matrix computations.

The 2017 John von Neumann Lecture prize is awarded to Bernard J. Matkowsky in recognition of his leading contributions to the methods and applications of matched asymptotics and singular perturbations. He has had a successful impact on applications to problems exhibiting resonance, the effect of noise on deterministic dynamical systems, bifurcation phenomena, and to pattern formation. He is an international leader in the mathematical theory of gaseous combustion and combustion synthesis. As an active member of SIAM and a key member of the Northwestern University Mathematics Department, he has inspired a host of excellent applied mathematicians.

The 2016 John von Neumann Lecture prize is awarded to Donald E. Knuth in recognition of his transformative contributions to mathematics and computer science. He founded the field of analysis of algorithms and gave it a rigorous mathematical footing. His ongoing *The Art of Computer Programming* book series represents the definitive reference on algorithms and their analysis. His TeX and Metafont typesetting software has changed the face of mathematical publishing and benefited every mathematician. He is a brilliant communicator at all levels, from his research monographs to his more popular books such as *Surreal Numbers* and his wonderful textbook *Concrete Mathematics*.

The 2014 John von Neumann Lecture prize is awarded to Leslie F. Greengard in recognition of his transformative contributions to computational science.Since the 1980s, when he and Rokhlin introduced the Fast Multipole Method, Greengard has shown the world the power of analysis-based algorithms for solving difficult computational problems of mathematical physics.He has changed our views of integral equations, particle simulations, spectral methods, fast Fourier transforms, and geometric complexity, inspiring students and colleagues at the Courant Institute and worldwide.

The 2013 John von Neumann Lecture is awarded to Stanley Osher in recognition of his extraordinarily influential and wide-ranging contributions to the computational sciences and engineering. Since the 1970s Stanley Osher has been a leader in developing mathematics and algorithms including essentially non-oscillatory methods for hyperbolic conservation laws, level set methods for front tracking, and l1 and TVD methods for image processing, tomography, and optimization. He has worked with an exceptionally large range of students, postdocs, and other collaborators, and his algorithms are used by scientists and engineers around the world.
