Judith Querida Longyear (20 September 1938–13 December 1995[1]) was an American mathematician and professor whose research interests included graph theory and combinatorics. Longyear earned her Ph.D. from Pennsylvania State University 1972, under the supervision of Sarvadaman Chowla, with a thesis entitled Tactical Configurations.[2][3] She taught mathematics at several universities including California Institute of Technology,[4] Dartmouth College[5] and Wayne State University.[6] She worked on nested block designs[4][7] and Hadamard matrices.[8]
