Former academic publisher Michael Holdsworth, 73, died September 9 of a heart attack while vacationing in France. Cambridge University Press, where he worked until 2006, called him, “Arguably the strongest publishing presence in the entire organization with a well-justified reputation as one of the most original, thoughtful and clear-sighted non-fiction book publishers in the world.” In addition to his accomplishments as a publisher, Holdsworth was a pioneer in converting much of CUP’s backlist to print on demand in the early days of the technology.
