Alison Des Forges, 66, Human Rights Advocate, Dies

Alison B. Liebhafsky was born Aug. 20, 1942, in Schenectady, N.Y., the daughter of Herman A. Liebhafsky, a chemist, and Sybil Small. She graduated from Radcliffe College in 1964 and received a master’s degree in 1966 and a doctorate in 1972, both in history, from Yale.

Her master’s thesis focused on the impact of European colonization on Rwanda’s social system, and her doctoral dissertation was about Yuhi Musinga, the mwami, or ruler, of Rwanda from 1896 to 1931, during which Germany, and later Belgium, colonized Rwanda.
