In Memoriam: S. Barry Cooper

It is with great sadness that we inform you of the passing away of Barry Cooper on Monday, 26 October. Barry has been a great inspiration to many of us. His work for establishing a truly interdisciplinary and open community around computability, through the CiE Association and the Turing celebrations, has been inspiring for the HaPoC community in many ways and will keep affecting our own work for many years to come. Barry was involved in various HaPoC events and under his presidency the Conference of the CiE Association established a HaPoC Special Session as part of the standard programme. His enthusiasm, passion and generosity have made this possible and will hopefully find echoes in our own research. The HaPoC Community, like so many involved in the study of computability and beyond, will miss him greatly.
