Rudolf Wille was a German mathematician and was professor of General Algebra from 1970 to 2003 at Technische Universität Darmstadt. His most celebrated work is the invention of formal concept analysis, an unsupervised machine learning technique that applies mathematical lattice theory to organize data based on objects and their shared attributes.
An accomplished musician and has also made contributions to Mathematics in Music, Mathematical Pedagogy and the Philosophy of Science, Wille played an active leadership role in the concept lattice research community.
Wille was a member of the Board of Directors of the Institute for Philosophy at TU Darmstadt from 1976. From 1983, was leader of the research group on Formal concept analysis and from 1993 Chairman of the "Ernst Schröder Center for Conceptual Knowledge Engineering". Wille was also a founding member of the Center for Inter-Disciplinary Research in Darmstadt and maintained a footprint in other research groups around the world as a visiting consulting/scholar.
