Upon receiving his doctorate, Newman taught for three years at Stonehill College, and then moved to Harvard University as Head Tutor in the History and Science Program. In 1996, he moved to Indiana University, where he has served both as faculty member and department chair. The history of medieval alchemy formed the central focus of Newman's early work, which included several studies of
Roger Bacon and culminated in an edition, translation, and study of the Latin alchemist who wrote under the assumed name of "
Geber" (a transliteration of "
Jābir", from "
Jābir ibn Hayyān"), probably
Paul of Taranto. In 1994, Newman published
Gehennical Fire, an intellectual biography of
George Starkey (otherwise known as
Eirenaeus Philalethes), a native of Bermuda who received his A.B. from
Harvard College in 1646 and went on to become
Robert Boyle's first serious tutor in chemistry and probably the favorite alchemical writer of
Isaac Newton. In 2002 and 2004, Newman and
Lawrence M. Principe expanded the study of Starkey’s relationship to Boyle with
Alchemy Tried in the Fire and also published the
Alchemical Laboratory Notebooks of Starkey. Following the lead set out in
Newman's
Gehennical Fire, the two authors argued that such terms as "early chemistry" and "alchemy" did scant justice to the expansive field in which figures like Starkey operated, so they advocated for a return to the archaic term "chymistry" in two seminal articles: this use of “chymistry” is now widely recognized, and has been acknowledged by the
Oxford English Dictionary (see the
OED entry for “Chemistry”). In 2004, Newman published
Promethean Ambitions, a work that explores alchemy’s important role as a focus for the widespread debate about the powers of art and nature in Western culture. His
Atoms and Alchemy, which argues that medieval and early modern alchemy were fundamental sources for the
mechanical philosophy of the 17th century, as well as for the approach to matter theory that Newman dubs "chymical atomism," appeared in 2006. Newman is General Editor of the
Chymistry of Isaac Newton project, which is editing Newton's alchemical writings and providing additional multimedia aids for deciphering them. ==Honors==
