He was rated among the top 62 ranking world social scientists since the beginning of the 20th century and was well known for his many contributions to multivariate analysis and basic theoretical matters in scientific research and statistics. Louis Gu t tman received both his undergraduate (BA, 1936) and graduate training (MA, 1939) at the University of Minnesota, earning his doctorate in social and psychological measurement in 1942. During his long and distinguished career he had multiple affiliations with both governmental and academic institutions. "He was the major force behind conducting a scientifically based job evaluation and classification of the Israel civil service as a basis for reform of its grading system."

A Note on the Eigensystem of the Covariance Matrix of Dichotomous Guttman Items
We consider the covariance matrix for dichotomous Guttman items under a set of uniformity conditions, and obtain closed-form expressions for the eigenvalues and eigenvectors of the matrix. In particular, we describe the eigenvalues and eigenvectors of the matrix in terms of trigonometric functions of the number of items. Our results parallel those of Zwick (1987) for the correlation matrix unde...
