Such a wonderful colleague, I miss Andy’s calming and witty presence in the department. So often his emails would make me laugh out loud; his way with words was always able to make a difficult situation seem so much better or brighten up a dull day.  I remember his humility when he was so right about something, saying “even a broken clock is right twice a day”! Such a pleasure to have worked with Andy, I just wish there’d been more time to get to know him better.
