Colin, founder and leader of the Glasgow (now West of Scotland) Parkinson’s Research Interest Group, passed away at the end of April. We all miss him; he was a lovely man and a great friend; he was passionate about research and always encouraged us to spread the word as widely as possible. He always had time for everyone, keeping in touch with our early members when their health deteriorated. His droll humour, delivered with his deadpan style, always entertained! Our memories of Colin and his long and productive life will live on.
