Peter F. Knowles (Emeritus Professor of the Astbury Centre, University of Leeds), Honorary Member of the BBS and previous committee member for many years, tragically died in a car accident on Thursday 3rd September 2015. He will be remembered for his boundless energy and enthusiasm in promoting biophysics, as an outstanding scientist, as well as a wise mentor and friend with an impish sense of humour. A genuinely “good person”, who will be sadly missed.

We note that RJP 'Bob' Williams died on the 21st of March 2015. Bob Williams was a pioneer of the field of Bioinorganic Chemistry, especially concerned with the role of metal ions as biological messengers, in electrolyte control and in enzyme catalysis, and contributed substantially to our understanding of the evolution of life.
