Donald Marquardt
View on WikipediaDonald W. Marquardt (March 13, 1929, New York City – July 5, 1997,[1] New Castle, Delaware) was an American statistician, the rediscoverer of the Levenberg–Marquardt nonlinear least squares fitting algorithm.[2]
Marquardt was educated at Columbia University with bachelor's degree in 1950 in physics and mathematics and at the University of Delaware with master's degree in 1956 in mathematics and statistics.[3] Marquardt joined DuPont in 1953 and worked there for 39 years. He also founded and managed the DuPont Quality Management & Technology Center.[1] In 1963 he published his famous paper "algorithm for least-squares estimation of nonlinear problems" in SIAM journal. Marquardt developed his algorithm to solve fitting nonlinear chemical models to laboratory data.[2] In 1975 he was elected as a Fellow of the American Statistical Association.[4]
As manager of the DuPont Applied Statistics Group, he led development of the Product Quality Management methodology and computer systems that implemented the company's continuous improvement initiatives from the mid-1970s to the late 1990s.[5] He won the Shewhart Medal in 1986.
