David Henkin is a professor of history at the University of California, Berkeley. His primary field of research is U.S. history, 19th Century America, urban history, and cultural history. He recently wrote a book, The Week: A History of the Unnatural Rhythms That Made Us Who We Are, that argues the week as a human’s artificial construction. He further illustrates how our daily lives have become attuned to seven days cycle. He is also the author of City Reading: Written Words and Public Spaces in Antebellum New York (Columbia University Press, 1998), The Postal Age: The Emergence of Modern Communications in Nineteenth-Century America (University of Chicago Press, 2006), and, with Rebecca McLennan, Becoming America: A History for the 21st Century (McGraw-Hill Education, 2014).
