Elizabeth Lawrence Cless was an American educator. She pioneered the development of continuing education for women, which provides new paths and programs to help women resume higher education that they had interrupted or postponed. Starting at the University of Minnesota in 1960, and subsequently at The Claremont Colleges in California, Cless developed and expanded the scope of those programs; by 1970 educators had created 400 of them throughout the United States. In 1979 she developed and founded The Plato Society, a lifelong learning organization at the University of California, Los Angeles focused on the intellectual growth of men and women over 50. Cless appears in Feminists Who Changed America, 1963–1975.
