We were very sad to hear of Colin's passing. We will remember him as a good friend, who it was always a great pleasure to see and to spend time with. Graham spent many hours (I would love to be able to say they were exclusively "happy" hours, but.....) with Colin at international meetings in Vienna; far more enjoyable were the many times boredom got the better of us and we stood chatting outside over coffee or talking sport (or watching it) in one of Vienna's many cafes and restaurants. Colin's advice and expertise was immensely helpful to Graham ; but more importantly he was warm, friendly, kind and generous, and someone who clearly loved, and was proud of, his family. We will always remember Colin with great fondness, and send our very best wishes to all his family. Unfortunately we will be unable to attend his funeral, as we will be in New Zealand; but will be thinking of him and you all.

So many happy childhood memories with Colin and his brother Gary and their Mum and Dad (Aunty Barbara and Uncle Ray) and other family members and their friends - we used to have a holiday with the family every year for a week - full of games in the family home and on the beach - any space to be honest! Full of friendly rivalry - happy times. Sending lots of love to Colin and his family xx

It was a great privilege to work with so many fine, able and congenial colleagues in my time at the Foreign Office; and Colin was just such a colleague and friend for many years as we toiled away in Vienna on CTBT issues. I will always remember the many great times we had in Flanagan's Irish pub for the Six Nations Rugby matches at weekends, especially when Wales (and Scotland) won; and at Steakpoint restaurant where Colin was the only person I had ever seen send a steak back twice because it wasn't well done enough to his liking! We all have such great memories of Colin, it's so sad that he has left us so soon.

To the family of Colin Waters. This news was so sad for my husband and I to hear. I worked with Colin, Attila, Dave, Sara, Aled, Owen and David for many years as part of the U.S. DOE/NNSA planning team (with Michele, Mike, Greg and Kurt) for all of the joint US-UK exercises that took place, up until the time when Colin and I both retired in late 2013. We have so many great memories of Colin, who rarely didn' have a smile to share. He was such a good natured person and and a joy to know! We were doing such important joint work but we always had fun while doing it! I have a couple of great videos of Colin and our joint team members singing karaoke at our house in VA as we celebrated after a long week of hard work in DC planning an exercise! I will see if I can send you a link for it at your email. With sympathy for your loss we will always consider Colin our dear friend and colleague. Sincerely, Jonna Murphy (and "Murph"

Thank you for setting up this memorial to Colin. We hope that you find it a positive experience developing the site and that it becomes a place of comfort and inspiration for you to visit whenever you want or need to.

I am I and you are you, whatever we were to each other that we still are. Speak to me in the easy way which you always used. Why should I be out of mind because I am out of sight? Life means all that it ever meant, it is the same as it ever was.
