Dear Colleagues, our member of the Editorial Board of Empirica, Professor Andrew Hughes Hallett deceased - already in December 2019. Springer has given me the permission to publish an obituary for HH in Empirica. I knew Andrew very well and would be prepared to write the obituary. Before doing this I would like to ask whether anyone of you knew HH even better than I and would therefore be prepared to write the obituary (1 page). If there is no reaction to my request in the next two weeks I will do it. Best regards, Fritz Breuss Managing Editor of Empirica
