Margaret Wilson, who died last year, has been described as the most eminent English-language historian of early modern philosophy of her generation. She was President of the Leibniz Society of North America for four years, from 1986 to 1990. Within this organization she is remembered both for her contributions to Leibniz-studies and for her attention to and support of younger researchers and her governing role in the Society. Her Harvard Ph.D. dissertation on “Leibniz’s Doctrine of Necessary Truth,” written under the (...) supervision of Morton White, was completed in 1965, and she went on to write a number of papers on Leibniz in the late 1960s and early-to-mid 1970s, including “Leibniz and Materialism,” “Confused Ideas” and “Leibniz’s Dynamics and Contingency in Nature,” returning to Leibniz in the late 1980s and early 1990s with such articles as “Compossibility and Law” and “The Phenomenalisms of Leibniz and Berkeley. ” Over the course of her career, Wilson published two books, her dissertation, which appeared in a series issued by Garland in 1990, and Descartes, published by Routledge and Kegan Paul in 1978, as well as more than thirty papers on seventeenth and eighteenth century philosophy, nearly all of which are included in the recent volume from Princeton University Press, Ideas and Mechanism. She held a number of research awards and honorary fellowships, including a Fellowship in the American Academy of Arts and Sciences to which she was elected in 1992. (shrink)
