I was shocked to hear the sad news. I had the opportunity to work with Professor Frew for a number years in Southampton both on the clinical side and in research on a number of projects. I will always remember Tony as an excellent and caring clinician, an inspiring and efficient leader and above all a very nice and an approachable person. He offered great mentorship for junior colleagues and was always supportive and created time. We will always remember his contribution to the world of allergy. My heartfelt condolences to Helen and family. Professor M Thirumala Krishna
