Harry Lewis, Gordon McKay Professor of Computer Science in the School of Engineering and Applied Sciences at Harvard University, is the author of numerous books and articles on computer science. A member of the Harvard faculty since 1974, he has helped launch thousands of Harvard undergraduates, including both Bill Gates and Mark Zuckerberg, into careers in computer science. His celebrated book about higher education, "Excellence Without a Soul: Does Liberal Education Have a Future?" was translated into Chinese (in both Taiwanese and mainland editions) and Korean. He is coauthor, with Hal Abelson and Ken Ledeen, of "Blown to Bits: Your Life, Liberty, and Happiness After the Digital Explosion" (translated into Russian and Chinese), which explains the origins and public consequences of the explosion of digital information. His most recent book, with Ellen Condliffe Lagemann, is the collection "What's College For? The Public Purpose of Higher Education." The editors contributed the lead essay, "Renewing The Civic Mission of American Higher Education."
