Hanno was Professor Emeritus in the University of Iowa’s School of Journalism and Mass Communication. He taught at Iowa for 33 years as the John F. Murray Professor of Journalism and Mass Communication. He also held a joint appointment in the Department of Communication Studies. After his retirement from Iowa in 2002, he continued his academic career at the University of Ljubljana in Slovenia, where he was professor on the Faculty of Social Sciences. He was the founder of EURICOM, the European Institute for Communication and Culture, and active in many professional associations. His work addressed a wide range of issues in communication and media studies, from critical theory to class politics in the newsroom to visual rhetorics. He published nine books and numerous journal articles that garnered him international renown. In addition to his scholarship on the media, he was an accomplished photographer; his photographic work included long-term projects in County Clare, Ireland, the eastern counties of Iowa, the former East Germany, and Slovenia. It ranges from street photography to documentations of community life, and landscapes. His photographs have been published in newspapers and magazines in the United States, Germany, and Slovenia. He has also exhibited his work in Iowa and in Slovenia.
During his time at Iowa, Hardt chaired more than 50 dissertations and is perhaps best remembered for his generous mentorship and support of graduate students and junior faculty. A Festschrift honoring his work was held at the University of Iowa in 2003, attended by former students and colleagues from all over the world.
