David M. Young Jr. (October 20, 1923 – December 21, 2008) was an American mathematician and computer scientist who was one of the pioneers in the field of modern numerical analysis/scientific computing.
Dr. Young is best known for establishing the mathematical framework for iterative methods (a.k.a. preconditioning). These algorithms are now used in computer software on high performance supercomputers for the numerical solution of large sparse linear systems arising from problems involving partial differential equations. See, in particular, the successive over-relaxation (SOR) and symmetric successive over-relaxation (SSOR) methods.
When David Young first began his research on iterative methods in the late 1940s, there was some skepticism with the idea of using iterative methods on the new computing machines to solve industrial-size problems. Ever since Young's ground-breaking Ph.D. thesis, iterative methods have been used on a wide range of scientific and engineering applications with a variety of new iterative methods having been developed.
David Young earned a bachelor's degree in 1944 from the Webb Institute of Naval Architecture. After service in the U.S. Navy during part of World War II, he went to Harvard University to study mathematics and was awarded a master's degree in 1947 and a Ph.D in 1950, working under the supervision of Professor Garrett Birkhoff. Young began his academic career at the University of Maryland, College Park and he was the first to teach a mathematics course focusing mainly on numerical analysis and computer programming. After several years working in the areo-space industry in Los Angeles, he joined the faculty of the University of Texas at Austin, Texas, in 1958. Dr. Young was the founding Director of the university Computation Center and then the research Center for Numerical Analysis (CNA) in 1970. He would become the Ashbel Smith Professor of Mathematics and Computer Sciences as well as a founding member of the Institute for Computational Engineering and Sciences (ICES), all at the University of Texas at Austin.
