I. Bernard Cohen, a Harvard scholar who published 20 books and 150 articles, died June 20. Cause of death was not released. He was 89.
Cohen joined the Harvard University faculty as an instructor in physics in 1942. He taught classes for more than four decades before retiring as a professor emeritus of the history of science.
Throughout his teaching career, Cohen constantly published his writing. He was best known as an expert on the subject of Isaac Newton. In 1957, Cohen decided to publish a comprehensive edition of Newton’s work in Latin. “Principia Mathematica” was finally finished in 1972; the 974-page, English translation was published in 1999.
Cohen’s final book, “The Triumph of Numbers,” was mailed to his publisher, W.W. Norton, two weeks ago.
