Obituary: Herbert Heyer, 1936–2018

Herbert Heyer, Emeritus Professor at the University of Tübingen, Germany, known for his research in stochastics and analysis has died. His close work with Japanese colleagues led the German–Japanese symposia on infinite-dimensional harmonic analysis; he also organized the Oberwolfach meeting series, Probability Measures on Groups. In the December 2016 issue of Communications on Stochastic Analysis, dedicated to Herbert on his 80th birthday, the editors note that he made “deep contributions to probability on locally compact groups, Polish groups and Gelfand pairs, with particular emphasis on Lévy–Khintchine/Hunt representations for infinitely divisible measures and associated convolution semigroups (and hemigroups), the central limit theorem, and the problem of embedding an infinitely divisible measure into a convolution semigroup. […] Herbert became a pioneer in developing harmonic analysis and probability theory on hypergroups.”

Welcome to the IMS Bulletin website! We are developing the way we communicate news and information more effectively with members. The print Bulletin is still with us (free with IMS membership), and still available as a PDF to download, but in addition, we are placing some of the news, columns and articles on this blog site, which will allow you the opportunity to interact more. We are always keen to hear from IMS members, and encourage you to write articles and reports that other IMS members would find interesting. Contact the IMS Bulletin at
