Judith Querida Longyear (20 September 1938[1]  - 13 December 1995[2]) was an American mathematician and professor whose research interests included graph theory and combinatorics. Longyear was the second woman to ever earn a mathematics Ph.D. from Pennsylvania State University,[3] where she studied under the supervision of Sarvadaman Chowla and wrote a thesis entitled Tactical Configurations.[4] Longyear taught mathematics at several universities including California Institute of Technology,[5] Dartmouth College[6] and Wayne State University.[7] She worked on nested block designs[5] [8] and Hadamard matrices.[9]
