Louis Guttman

[1] Louis (Eliyahu) Guttman was born in New York City and grew up in the Jewish community of Minneapolis, Minnesota.From 1941 to 1947 Guttman was professor of sociology at Cornell University, while as part of the World War II effort, he also served as an Expert Consultant to the US Army's Research Branch.[5] Later, searching for a more flexible scaling scheme, Guttman explored Partial Order Scalogram Analysis (POSA) and applied it in empirical studies.Notably, Guttman first proved several fundamental theorems in matrix algebra, as discussed in papers by Hubert, Meulman and Heiser (2000)[6] and Takane and Yanai (2005).[7][verification needed] Guttman published in numerous journals and books, including over 300 pages in Psychometrika.
