Dolf Zillmann (born March 12, 1935) is dean emeritus, and professor of information sciences, communication and psychology at the University of Alabama (UA). Zillmann predominantly conducted research in media psychology, a branch of psychology focused on the effects of media consumption on human affect, developing and expanding a range of theories within media psychology and communication. His work centred on the relation between aggression, emotion, and arousal through media consumption, predominantly in pornography and violent genres of movie and television. His research also includes the effects of music consumption, video games, and sports.

Zillmann's influence within both the fields of media psychology and communication was highlighted by Ellen Baker Derwin and Janet De Merode finding Zillmann to be the seventh most contributing media psychology author between 1999 and 2010.

Born in the former Province of Brandenburg, in the now Polish town of Meseritz, Zillmann's birthplace was highly contended, changing hands between German, Polish and Soviet forces throughout the duration of the Second World War. Much of his early educational experiences in the Western region of Poland took place in underfunded and understaffed educational institutions. Within Poland, roughly 20 percent of the population over the age of 10 were illiterate. Many of the primary schools had been closed, instead being utilised as hospitals for soldiers. Those schools that were open were highly filtered and structured through the Nazi ideology for the education of Slavs.

With his Father's conscription into the war, later death, and the contention in the area his family resided, Zillmann, along with his mother and sister, spent the majority of the war fleeing violence, leading to poor living conditions throughout most of his youth, irrespective of his family's affluence in Meseritz. Eventually, he and his family would settle in Marburg, a university town in the Hessen Region of Germany. Zillmann was self-taught, his only means of gaining an education due to the widespread post-war resource shortages.

Zillmann would continue on to higher education studying German architecture at the Ulm School of Design, a new Bauhaus School of Architecture which had been re-opened by the Swiss architect Max Bill after its closure by Nazi authorities during the war. After the acquisition of his diploma in architecture in 1955, he began working with Max Bill, entering architecture competitions in Zurich, beginning city planning in Isfahan, and designing and planning several public projects in many other European cities.

Zillmann would go back to formal study at the Ulm School, studying in the fields of communication and cybernetics, engaging with many different academics in the field outside of Ulm such as the German aesthetics philosopher Max Bense at the University of Stuttgart and Professor of visual science Herbert Schober at the University of Munich. Zillmann would acquire his diploma in communication and cybernetics in 1959 while also working as a scientific advisor for a holding company in Zurich. Zillmann's role predominantly involved the practical application of communications research to assist in marketing campaigns for several of the companies it parented, working there from 1959 - 1965.

In 1968, Zillmann moved to the United States in Madison, Wisconsin, where he was a doctoral student in communication and psychology at the University of Wisconsin. He would then move to Philadelphia in 1969, working in the University of Pennsylvania, which houses the oldest psychology department in North America, going on to acquire a doctorate in communication and social psychology there that same year from the Annenberg School. He would work as an assistant professor there until 1971, and would hold the position of associate professor from 1971 to 1975, teaching a range of subjects in both communication, psychology and general scientific methodology. It is during this time that the underpinnings of his excitation transfer theory were being tested and published.

Following his time at Philadelphia, Zillmann accepted an appointment as an associate professor and subsequently a full Professorial appointment in Communication and Psychology between 1975 and 1988 at Indiana University. Whilst continuing his own research Zillmann also established the Institute for Communications Research (ICR) at the university, Zillmann acting as the Director of the ICR from 1974 - 1988. The focus of the ICR is on both communication research and wider social scientific research in the field of media consumption, operating within Indiana University.
