photo neededIn chemistry, Alistair Matheson Duncan (c.1941-), otherwise known as A.M. Duncan, is an English chemistry historian, whose specific focus is 18th century chemistry, in particular affinity chemistry and the use of affinity tables. Of note, Duncan wrote the 30-page introduction section to the 1970 edition of Swedish chemist Torbern Bergman's 1775 A Dissertation on Elective Attractions. [1]

Education
Duncan completed his 1971 PhD on “Eighteenth-Century Theories of Chemical Affinity and Attraction” at the University of London. [2] In circa 1980, Duncan was in contact with German science historian Jeremy Adler and gave him direction and guidance with his research on the affinity chemistry behind Goethe’s Elective Affinities.
