Carolyn Marvin is the Frances Yates Professor of Communication at the Annenberg School for Communication. Professor Marvin's research focuses on the relationship between cultural discourses and what they run up against or are limited by, including the human body, material space, and social boundaries. She also has an interest in the related areas of ritual communication and freedom of expression. Professor Marvin is the author of When Old Technologies Were New (1988), a history of how new electric communication technologies at the end of the 19th century were received by a coterie of electrical engineers whose emerging professional status depended on convincing the public of the utility of these inventions and their expertise in relation to them. Also at issue was their reception by a public that feared and anticipated the rearrangement of customary social distances by the new forms of access and transparency these inventions made possible. This study concerns how new conventions of social trust must be negotiated around technological change. In 2010 this book was named the best book on technology ever written in the Atlantic Tech Canon’s first survey of the 50 best books on technology. Dr. Marvin also authored Blood Sacrifice and the Nation: Totem Rituals and the Flag (Cambridge University Press, 1999), which proposes that American patriotism is a civil religion more culturally far-reaching, more symbolically intricate, and far more violent than previous theories of civil religion have allowed. This study of civil religion examines wars as national sacrifice rituals, presidential elections as national fertility rituals, and both as central to the consciousness of citizens as members of a national community. Dr. Marvin completed her Ph.D. at the University of Illinois and has won the Franklyn S. Haiman Award for Outstanding Scholarship in Freedom of Expression from the Speech Communications Association and the Lindback Foundation Award for Distinguished Teaching at the University of Pennsylvania.
