For two years, from 1940 to 1942, he was a visiting scholar at the Institute for Advanced Study. During WW II he began to study operations research and development of mathematical models for military applications. From 1957 to 1961 he was the editor-in-chief of Management Science, as successor to C. West Churchman. From 1961 to 1965 Thrall was an associate editor for the journal. He was the 16th president of The Institute of Management Sciences for a one-year term in 1969–1970. He was elected to the 2002 class of Fellows of the Institute for Operations Research and the Management Sciences. With William W. Cooper, Rajiv Banker, and other collaborators, he wrote a number of important papers on data envelopment analysis. Thrall was the author or co-author of over 100 articles in scholarly journals, as well as several books.
He married Natalie Hunter in 1936. His wife died in 2004. Upon his death he was survived by a daughter, two sons, three grandchildren, and three great-grandchildren.Selected publications
