Elliott Ward Cheney Jr.

Elliott Ward Cheney Jr. (June 28, 1929 – July 13, 2016) was an American mathematician and an Emeritus Professor at the University of Texas at Austin.[1] Known to his friends and colleagues as Ward Cheney, he was one of the pioneers in the fields of approximation theory and numerical analysis.[2] His 1966 book, An Introduction to Approximation Theory, remains in print and is "highly respected and well known", "a small book almost encyclopedic in character", and "is a classic with few competitors".[3][4]

Education and personal life

The second of two children of E. W. Cheney, Sr., and Carleton (Pratt) Cheney, Elliott Ward Cheney Jr., was born in Gettysburg, Pennsylvania, and grew up in Washington, D.C., New Jersey, and Bethlehem, Pennsylvania.[5]:1 Ward began clarinet studies at age ten and would play in chamber music groups throughout his life.[6]

Ward Cheney was a 1947 graduate of Fountain Hill High School, Bethlehem, Pennsylvania. In 1951, he earned his bachelor's degree in mathematics from Lehigh University, where his father was a physics professor. During undergraduate summers, Ward worked for the United States Forest Service, where he met Elizabeth Jean "Beth", whom he married in 1952. The young couple resided in Lawrence, Kansas, while Ward studied and served as a mathematics instructor at The University of Kansas, earning his Ph.D. in 1957.[7] Ward had three children with his first wife, Beth, all of whom earned doctorates: daughter Margaret is a professor of mathematics,[8] son David is a manager of international research projects,[9] and son Elliott is a professional cellist.[10] Their mother Beth remarried in 1975 and died in 1991. Ward and his wife Victoria had been together since 1983.

Professional background

Following the launch of Sputnik 1 by the Soviet Union in 1957, the United States intensified its focus on their aerospace program. Cheney became a research scientist at Convair Astronautics in San Diego, California, where his mathematical team worked on calculations for the Atlas rocket—which would take John Glenn into space.

Cheney also worked for Space Technology, near Los Angeles, and taught at UCLA, with visiting positions at Michigan State University and Iowa State University. In addition, Ward was a consultant and/or a guest worker at Boeing Scientific Research Laboratories, The Aerospace Corporation, and IBM Research Laboratory. In the summers of 1961–63, he was director of the NSF Summer Institute in Numerical Analysis at the University of California, Los Angeles.[5]:1

In 1964, Ward joined the mathematics faculty of The University of Texas at Austin, where he taught for the next 41 years, until his retirement at age 76.[1]

Career and travel

Cheney served continuously on the editorial board of the Journal of Approximation Theory from its inception in 1968 until sometime after the start of 2015, and published 14 papers there.[11][12]

Professor Cheney supervised 17 PhD students,[7] 35 Masters students, and worked with three post-doctoral students.[5]:12–13 He was Associate Editor for ten mathematical journals as well as referee and reviewer for many other journals.[5]:11–12 Cheney had over a 100 published papers and was the author of two dozen mathematical textbooks, with several having multiple editions.[5]:2–6 A reviewer wrote of his 1986 monograph: "Cheney's book scores highly on all ... points". Ward Cheney and Will Light wrote two graduate level books. Ward Cheney and David Kincaid co-authored two undergraduate textbooks, and a graduate textbook.

During his career, Ward frequently spent his summers and a sabbatical semester in England at Lancaster University and at Leicester University. Also, he held a visiting professorship at Lund University, Sweden. Ward was a world-wide traveler and was frequently invited to give lecturers on approximation theory at universities wherever he went.[5]:6–10

Teaching and research

Ward was an inspirational teacher and a superb lecturer who presented over 165 invited lectures and colloquium talks at universities and conferences around the world.[5]:6–10 Special honors include an invited lectures at the 1963 National Meeting of the Society for Industrial and Applied Mathematics (SIAM), in Denver, Colorado, and at the 1974 International Congress of Mathematicians, in Vancouver, Canada. Moreover, Professor Cheney was the honoree at the 1995 International Conference on Approximation Theory, College Station, Texas.[5]:11 For over 40 years, this has been the main general conference on approximation theory with presentations by international mathematician from academia, industry, and government.[13]

Cheney was awarded grants for his research on approximation theory from the National Science Foundation, United States Air Force and United States Army as well as the UK Research Councils and the Italian Scientific Research Council, among others.[5]:11

In 2012, Ward became a Fellow of the American Mathematical Society, which was the first year the honor was awarded.[14]

Cheney died in July 2016, after having had Alzheimer's disease for several years.

gollark: I don't really have many practical ideas now, """ sorry """.
gollark: The best calculator around now is arguably the HP Prime, but it's very costly. There are used ones extant however. Probably.
gollark: There are some Casio graphing calculators some of my friends have with python but yes, cost.
