Obituary of William Rosen

Author William Rosen, whose works of narrative nonfiction include “Justinian’s Flea” and “The Most Powerful Idea in the World: The Story of Steam, Industry and Invention” died at home on April 28, 2016, of gastrointestinal stromal cancer, according to his agent. He was 61. Born in California, Rosen worked for nearly twenty-five years as an editor and publisher at MacMillan, Simon & Schuster and the Free Press, before becoming an author. With a writing style that used anecdote to pull together the threads of discovery and innovation, Rosen authored or co-authored books on education, traffic, antibiotics, and climate change. Bill Gates said of Rosen’s work: “Rosen argues that only with the ability to measure incremental advances—such as whether a lighter part lowers fuel consumption, or one engine produces more power than another—can you achieve sustained innovation. Rosen’s view fits my own view of the power of measurement….” Rosen grew up in Los Angeles, attended UCLA, and after a brief stint at John Wiley and Sons moved east for publishing. He edited books authored by George Will, as well as William Bennett, Bernard Lewis, Maya Lin, and Leon Kass. But he found true fulfillment writing books instead of only publishing them. Rosen lived in Princeton, New Jersey and is survived by his wife Jeanine; two daughters, Quillan and Emma; a son, Alex; and his brother Gary and sister-in-law Holly.
