Influenced by him, and probably even more so by my brother Theodore a year older than me, I soon became interested in biology and developed a respect for the importance of science and the scientific method.

When I was young my Father used to tell me that the two most worthwhile pursuits in life were the pursuit of truth and of beauty and I believe that Alfred Nobel must have felt much the same when he gave these prizes for literature and the sciences.

Through art and science in their broadest senses it is possible to make a permanent contribution towards the improvement and enrichment of human life and it is these pursuits that we students are engaged in.

And indeed this theme has been at the centre of all my research since 1943, both because of its intrinsic fascination and my conviction that a knowledge of sequences could contribute much to our understanding of living matter.

Scientific research is one of the most exciting and rewarding of occupations.

After taking my B.A. degree in 1939 I remained at the University for a further year to take an advanced course in Biochemistry, and surprised myself and my teachers by obtaining a first class examination result.

Initially I had intended to study medicine, but before going to University I had decided that I would be better suited to a career in which I could concentrate my activities and interests more on a single goal than appeared to be possible in my father's profession.
