Biography

Louis (Eliyahu) Guttman was born in New York City and grew up in the Jewish community of Minneapolis, Minnesota. Guttman received both his BA in 1936 and MA in 1939 at the University of Minnesota, and his PhD in Social and Psychological Measurement in 1942. In 1947 Guttman and his wife Ruth immmigrated to Palestine.

Guttman died on October 25, 1987, while on sabbatical in Minneapolis.

Academic career

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.

He founded and was the scientific director of the Israel Institute of Applied Social Research, later renamed the Guttman Institute before finally becoming the Guttman Center for Public Opinion and Policy Research.{{citation needed|date=January 2021}}

He was member of the Israel Academy of Sciences and Humanities, and foreign Honorary member of the American Academy of Arts and Sciences and President of the Psychometric Society. In 1956 he was elected a Fellow at the Center for Advanced Study in the Behavioral Sciences. In 1962 he received the Rothschild Prize. The development of scaling theory by Louis Guttman and Clyde Coombs has been recognized by Science as one of 62 major advances in the social sciences in the period 1900-1965.Deutsch, K.W., Platt, J. & Sengham, D. (1971). Conditions favoring major advances in social sciences. Science 05 Feb 1971: Vol. 171, Issue 3970, pp. 450-459. {{doi|10.1126/science.171.3970.450}}

Work

Guttman research interests were in the fields of scale and factor analysis, multidimensional scaling and facet theory.{{cite encyclopedia |last=Shye |first=S. |editor1-last=Kotz |editor1-first=S. |encyclopedia=Encyclopedia of Statistical Sciences Update Vol. 3 |title=Facet Theory |date=1999 |publisher=New York: Wiley |isbn=0-471-23883-X |pages=231–239}} His mathematical and philosophical treatments of Factor analysis are among the important parts of his scientific legacy.

His earlier work in scaling analysis produced what has become to be known as the Guttman scale.Stouffer, S.A., Guttman, L., Suchman, E.A., Lazarsfeld, P.F., Star, S.A., Clausen, J.A. (1950) [https://academic.oup.com/sf/article/29/2/207/2225654 Measurement and Prediction] Princeton University Press 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){{cite book | author=Lawrence J. Hubert, Phipps Arabie, Jacqueline Meulman | title=Combinatorial Data Analysis: Optimization by Dynamic Programming | publisher=SIAM | year=2001 | isbn=978-0898714784}} and Takane and Yanai (2005). Several of Guttman's contributions, such as Smallest Space Analysis (SSA), have been incorporated into computer packages.

Guttman was described{{by whom|date=January 2021}} as a brilliant innovator who "saw theory in method and method in theory", was "informed by high sophistication in mathematics, statistics, sociology and psychology", and one who "made a major contribution to democratic policy-making in the new state" and "was concerned with the 'well-being' of individuals, groups and society".(from a posthumous award ceremony by the World Association of Public Opinion Research, 1988){{verification needed|date=January 2021}}

Guttman published in numerous journals and books, including over 300 pages in Psychometrika. Many of his papers are still quoted in the scientific literature as being relevant and important to current statistical and mathematical advances.

His innovative methodological work on attitudes was published in the 4th volume of Studies in Social Psychology in World War II (more popularly called The American Soldier series, after the title of the first two volumes).
