He was awarded the Corday-Morgan medal in 1953, Royal Medal in 1976 and the Copley Medal in 1982.
He is a member of the Royal Society and is still very active in chemistry research at the University of Sussex. This section from longer archive recordings shows his warmth and personality, and gives an insight into an amazing man who has overcome deafness to pursue a brilliant career in science. He was named the Australian of the Year in 1975.
