# Kurt Weichselberger’s Contribution to Imprecise Probabilities

*Proceedings of the Tenth International Symposium on Imprecise Probability: Theories and Applications*, PMLR 62:13-24, 2017.

#### Abstract

Kurt Weichselberger, one of the influential senior members of the imprecise probability community, passed away on February 7, 2016. Almost throughout his entire academic life the major focus of his research interest has been on the foundations of probability and statistics. The present article is a first attempt to trace back chronologically the development of Weichselberger’s work on interval probability and his symmetric theory of logical probability based on it. We also try to work out the intellectual background of his different projects together with some close links between them.
