Elizabeth Hahnemann Cuthill (October 16, 1923 – January 11, 2011)[1] was an American applied mathematician and numerical analyst known for her work on sparse matrix algorithms, on block iterative methods for the numerical approximation of differential equations, and on the development of computer simulations of nuclear reactors.
She was a researcher for the United States Navy at the David Taylor Model Basin.
[2] The Cuthill–McKee algorithm and reverse Cuthill–McKee algorithm are heuristics for permuting matrices into forms with small bandwidth and for associated problems in graph bandwidth, named for the work of Cuthill with James McKee.
[4] After this, she completed a Ph.D. at the University of Minnesota in 1951; her dissertation, Integrals on Spaces of Functions which are Real and Continuous on Finite and Infinite Intervals, was supervised by Robert Horton Cameron.
[6] In 1953, she became a researcher for the United States Navy, working at the David Taylor Model Basin, where she became Numerical Analysis Coordinator for the Computation, Mathematics, and Logistics Department.
