When Warren Kendall Lewis left Spring Garden Farm in Delaware in 1901 to enter MIT, he had no idea that he was becoming part of a profession that would bring untold good to his country but would also contribute to the death of his family’s farm. In this book written a century later, Professor Lewis’s granddaughter, a cultural historian who has served in the administration of MIT, uses her grandfather’s and her own experience to make sense of the rapidly changing role of technology in contemporary life.
