Helen was one of the greatest minds in animal health. She could turn up to any meeting and would always be the authority on the subject. She was generous with her knowledge and taught so many of us about risk assessment and disease control. As a result of  her diligence, she has had a profound impact on the health of animals and people on a global scale and that legacy will live on. I am shocked and saddended that she is gone, but am so grateful to have known her and enjoyed a few drinks in Marquis of Granby.  Thank you for all that you did Helen! We will miss you
