Joseph Bernard Kruskal, Jr. (/ˈkrʌskəl/; January 29, 1928 – September 19, 2010) was an American mathematician, statistician, computer scientist and psychometrician.
Kruskal was born to a Jewish family in New York City to a successful fur wholesaler, Joseph B. Kruskal, Sr. His mother, Lillian Rose Vorhaus Kruskal Oppenheimer, became a noted promoter of Origami during the early era of television.
Kruskal had two notable brothers, Martin David Kruskal, co-inventor of solitons and of surreal numbers, and William Kruskal who developed the Kruskal-Wallis one-way analysis of variance. One of Joseph Kruskal's nephews is computer scientist Clyde Kruskal.
He was a student at the University of Chicago earning a bachelor of science in mathematics in the year of 1948, and a master of science in mathematics in the following year 1949. After his time at the University of Chicago Kruskal attended Princeton University, where he completed his Ph.D. in 1954, nominally under Albert W. Tucker and Roger Lyndon, but de facto under Paul Erdős with whom he had two very short conversations. Kruskal has worked on well-quasi-orderings and multidimensional scaling.
