Walter Edwin Arnoldi

Walter Edwin Arnoldi ( born December 14, 1917 in New York City; † 5 October 1995) was an American mechanical engineer, known for work on numerical linear algebra.

Arnoldi took his degree in 1937 as an engineer at Stevens Institute of Technology and then studied at Harvard University with a master's degree in 1939 (MS). He then worked from 1939 to his retirement in 1977 as an engineer for United Aircraft Corporation, for which he hired to primarily mechanical calculations and aerodynamic characteristics of aircraft design. He also had problems of linear algebra to solve, which led to his development of the eponymous Arnoldi method, which he published in 1951. He was a senior engineer in the Hamilton Standard Division of United Aircraft Corporation.
