Joseph Bernard Kruskal, Jr. (29 January 1928 to 19 September 2010) was an American mathematician. Born in New York City to a Jewish family, he was a student at the University of Chicago, earning a bachelor of science in mathematics in 1948 and a master of science the following year, and completed his Ph.D. at Princeton University in 1954. He worked on well-quasi-orderings and multidimensional scaling. He was a Fellow of the American Statistical Association and a former president of the Psychometric Society and of the Classification Society of North America. His brothers were Martin David Kruskal, co-inventor of solitons, and William Kruskal, who developed the Kruskal-Wallis one-way analysis of variance.
