Reference excerpt

Klaus Krippendorff (March 21, 1932 – October 10, 2022) was a communication scholar, social science methodologist, and cyberneticist. and was the Gregory Bateson professor for Cybernetics, Language, and Culture at the University of Pennsylvania's Annenberg School for Communication. He wrote an influential textbook on content analysis and is the creator of the widely used and eponymous measure of interrater reliability, Krippendorff's alpha. In 1984–1985, he served as the president of the International Communication Association, one of the two largest professional associations for scholars of communication.

Overview Krippendorff was born in 1932 in Frankfurt am Main in Germany. His father was an engineer at Junkers. In 1954, he graduated with an engineering degree from the State Engineering School Hannover (now Hanover University of Applied Sciences and Arts). In 1961, he graduated as diplom-designer from the 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 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 Urbana-Champaign. In 1964, he joined the Annenberg School for Communication at the University of Pennsylvania. He was a member of the editorial boards of multiple 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. 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 a fellow of the American Association for the Advancement of Science (AAAS) in 1982, a fellow of the International Communication Association (ICA) in 1985, and a fellow of the Japanese Society for Science and Design Studies in 1998. In 1998, graduate students named him as the teacher of the best doctoral 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. 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 the 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.

Personal life He was married to Bangladeshi freedom fighter Sultana Alam. Two of his grandsons are professional soccer players Quinn Sullivan and Cavan Sullivan. Additionally, his twin grandsons, Ronan Sullivan and Declan Sullivan represent Bangladesh at youth level due to Krippendorff's wife's Bangladeshi heritage. Another grandson, Lucas, is an electrical engineering major at the University of Pennsylvania. Krippendorff died at the age of 90 in October 2022.

Selected publications Krippendorff has published widely on cybernetics and systems theory, methodology in the social sciences, human communication, conversation, and discourse. Among his major works are the following:

Worked examples

Example 1 — a first encounter with Klaus Krippendorff

Start with the simplest possible case. Write down what Klaus Krippendorff claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Klaus Krippendorff before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Klaus Krippendorff ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Klaus Krippendorff

In research: Klaus Krippendorff appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Klaus Krippendorff in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Klaus Krippendorff is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1932 births, 2022 deaths, Alumni of the Ulm School of Design, so understanding it makes those chapters shorter.
In everyday life: Look for Klaus Krippendorff outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
