Subject: Robert J. Plemmons (1938–2026)
Robert J. Plemmons passed away on February 6, 2026, at the age of
87. Born in Old Fort, North Carolina in 1938, he earned his B.S. in
mathematics from Wake Forest University in 1962 and his Ph.D. from
Auburn University in 1965, working primarily with Emilie Haynesworth.
Bob held positions at the National Security Agency and The Martin
Company, as well as academic appointments at the University of
Mississippi, the University of Tennessee (where he met his mentor
Alston Householder), and North Carolina State University. In 1990, he
returned to Wake Forest University as the Z. Smith Reynolds Professor
of Mathematics and Computer Science. He retired from teaching in 2013
but remained active in research thereafter.
Bob’s research career began in semigroup theory and finite algebraic
systems, with his first publication appearing in 1965. In the early
1970s, he shifted toward matrix theory, making foundational
contributions to generalized inverses, nonnegative matrices, and
M-matrices. His work significantly advanced the numerical analysis of
singular and rectangular linear systems, extending classical results
for nonsingular problems. A major highlight of this period was his
collaboration with Avi Berman, which led to the influential 1979 book
Nonnegative Matrices in the Mathematical Sciences. Widely regarded as
a cornerstone of the field, the book was republished by SIAM in 1994
as a Classic in Applied Mathematics.
In later years, Bob contributed extensively to large sparse least
squares problems, Markov chains, matrix factorizations, and,
eventually, to applications in signal and image processing. His work
encompassed recursive least squares, FFT-based preconditioning, and
adaptive optics for ground- based telescope imaging. Even in
retirement, he continued this research with support from the Air Force
Office of Scientific Research and the National Aeronautics and Space
Administration, focusing on space situational awareness and remote
sensing. Bob's work was recognized by many awards, including being
named a SIAM Fellow in 2013.
Bob was also deeply committed to service, acting as a journal editor,
conference organizer, and advocate for the mathematical
sciences. Outside academia, Bob was a gifted athlete who played
baseball in the Baltimore Orioles farm system, an avid fisherman and
gardener, and a licensed pilot. Known especially for his kindness and
generosity, Bob Plemmons will be fondly remembered and greatly missed.
A more extensive biography of Bob's early career was published in 2000
issue of Linear Algebra and its Applications in celebration of Bob's 60th
birthday;

2026 Colorado Conference on Iterative and Multigrid Methods
Sunday June 21 - Friday June 26, 2026
Boulder, Colorado, USA
The Copper Mountain Conference on Multigrid Methods was founded in
1983 and held every two years (odd years) since then. In 1990, the
Copper Mountain Conference on Iterative Methods was formed as a
companion conference to be held in even years. Together, they are
widely regarded as premier international conferences on iterative and
multigrid methods. In 2026, we continue this conference series with
the Colorado Conference on Iterative and Multigrid Methods to be held
on the CU Boulder campus.
Abstract submission for the conference will soon open, including for
the student paper competition (a tradition at the meeting with a cash
award). For more information, see our website at
