I was very sorry to hear the sad news that Tony has passed away. I had the opportunity of knowing him by serving on the same occupational diseases committees of AAAAI and WAO, and of being a co-speaker in seminars on occupational asthma at AAAAI meetings. It was a delight to have known him. He was a very practical and clear thinker and was very courteous in considering all opinions. My condolences to his family.
