Herbert Wilf, American mathematician and academic (b. 1931)

Herbert Saul Wilf (June 13, 1931 – January 7, 2012) was an exceptionally influential American mathematician, whose extensive work profoundly impacted the fields of combinatorics and graph theory. Renowned for his clarity, innovative research, and pioneering efforts in open access scholarly publishing, Wilf left an enduring legacy in discrete mathematics, bridging theoretical advancements with practical computational applications.

Dr. Wilf's primary specialization was in combinatorics, a core branch of discrete mathematics focused on the study of finite or countable discrete structures. This includes enumeration (counting problems), existence (determining if certain configurations are possible), construction (creating such configurations), and optimization (finding the "best" configurations). Closely related to this, he also specialized in graph theory, which investigates graphs – mathematical structures composed of vertices (nodes) and edges (connections) – used to model pairwise relations between objects. His research frequently involved the elegant application of generating functions to resolve complex enumeration challenges, a powerful analytical technique that transforms combinatorial problems into more manageable algebraic ones. He was particularly celebrated for his contributions to algorithmic combinatorics, developing efficient computational methods for solving intricate combinatorial problems. Through his collaborative projects and influential textbooks, Wilf shaped the understanding and application of these sophisticated mathematical domains for generations of scholars and students globally.

Academically, Herbert Wilf held the distinguished position of Thomas A. Scott Professor of Mathematics in Combinatorial Analysis and Computing at the University of Pennsylvania. This endowed professorship underscored his prominent standing within the mathematical community and highlighted the university's recognition of the critical importance of his specialized research areas. His tenure at such a prestigious institution enabled him to cultivate a dynamic research environment and significantly mentor numerous emerging mathematicians at the forefront of computational and combinatorial mathematics.

Throughout his prolific career, Wilf authored and co-authored numerous seminal books and groundbreaking research papers. His publications were consistently acclaimed for their intellectual rigor, accessibility, and the innovative problem-solving approaches they presented. Among his most celebrated works is "A=B," co-authored with Doron Zeilberger and Marko Petkovšek, a book that revolutionized the use of computer-assisted proof methods for identities involving sums and products. Another highly influential text, "Generatingfunctionology," became a standard, widely referenced resource for students and researchers exploring the profound capabilities of generating functions in solving combinatorial problems.

A true visionary in the realm of academic publishing, Herbert Wilf co-founded The Electronic Journal of Combinatorics (EJC) with Neil Calkin in 1994. This initiative was remarkably progressive for its time, establishing EJC as one of the very first peer-reviewed, open-access electronic journals in mathematics. His dedicated leadership as editor-in-chief until 2001 was instrumental in cementing EJC's reputation for disseminating high-quality research and its unwavering commitment to making cutting-edge mathematical scholarship freely accessible to a global audience. The journal's pioneering model significantly influenced the burgeoning movement towards open access publishing in academia, conclusively demonstrating the viability, immense benefit, and critical importance of online dissemination of research.
