"Don's contributions to our understanding of immune system function and viral infection have had an extraordinary impact. He tackled important biological problems with a precision, clarity and insight that was inspirational. Over the last thirty years Don has been a vital force in our Department. His combination of energy, boyish enthusiasm and sharp intellect has played a major role in all of our activities. His absence leaves a great void." - Andy McMahon, Chairman, MCB
