This volume honors the lifetime achievements of the distinguished activist and scholar Elise Boulding (1920–2010) on the occasion of her 95th birthday. Known as the “matriarch” of the twentieth century peace research movement, she made significant contributions in the fields of peace education, future studies, feminism, and sociology of the family, and as a prominent leader in the peace movement and the Society of Friends. She taught at the University of Colorado, Boulder from 1967 to 1978 and at Dartmouth College from 1978 to 1985, and was instrumental in the development of peace studies programs at both institutions. She was a co-founder of the International Peace Research Association (1964), the Consortium on Peace Research Education and Development (1970), and various peace and women’s issues-related committees and working groups of the American Sociological Association and International Sociological Association.
