Klaus Krippendorff was born in 1932 in Frankfurt am Main in Germany. In 1954, he graduated with an engineering degree from the State Engineering School Hannover. In 1961, he graduated as diplom-designer from the internationally famed avantgarde Ulm School of Design (Hochschule für Gestaltung Ulm), Germany. And in 1967, he received his Ph.D. in communications from the pioneering Institute for Communication Research at the University of Illinois at Urbana-Champaign.
Krippendorff started to work as an engineer and during the last year of his graduate study of design he was a Research Assistant at the Institute for Visual Perception at the Ulm School of Design. In 1961 he came to the United States with a two-year Ford International Fellowship, first to Princeton University but completing his second graduate education at the University of Illinois at Urbana-Champaign. In 1964, he joined the Annenberg School for Communication at the University of Pennsylvania, where he is a professor of communication.
He is or was a member of the editorial boards of some 20 academic journals, such as Communication and Information Science, Communication Research, Constructivist Foundations, Cybernetics & Human Knowing, International Journal of Cultural Studies and the Journal of Communication. He reviewed for many instutitutions and journals from the U.S. National Science Foundation (NSF) and Austrian, Israeli, and Swiss Science Foundations to The Sociological Quarterly, the Journal of the American Statistical Association, Journal for Peace Research, the Management Communication Quarterly and the Journalism: Theory, Practice & Criticism.
In 1971, he was awarded an honorary MA from the University of Pennsylvania. In the same year, he received an Award for "On Generating Data in Communication Research" as the most outstanding contribution to The Journal of Communication, published in 1970. In 1979, he became a Fellow of the Netherlands Institute for Advanced Study in the Humanities and Social Sciences. He was elected fellow of the American Association for the Advancement of Science (AAAS) in 1982, fellow of the International Communication Association (ICA) in 1985, and fellow of the Japanese Society for Science and Design Studies in 1998.
In 1998, graduate students named him as the teacher of the best doctorial course taken at the University of Pennsylvania. In 2000, he became the Gregory Bateson professor for Cybernetics, Language, and Culture at the Annenberg School for Communication. In 2001 he was awarded the Norbert Wiener Medal in Cybernetics in gold by the American Society for Cybernetics for his contributions to cybernetics. Also in 2001, he received the ICA Fellows Book Award for his influential text Content Analysis, An Introduction to Its Methodology. In 2004, he received the Norbert Wiener/Hermann Schmidt Prize from the German Society for Cybernetics and German Society for Pedagogy and Information, at the University of Vienna.
In 2012, the Linnaeus University in Kalmar/Växjö, Sweden, awarded him the degree of Doctor of Philosophy honoris causa.
