I and my colleagues here have been engaged in the pursuit of knowledge.

In this atmosphere I soon became interested in nucleic acids.

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

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.

Science is not like the Olympic Games or something where there's a lot of people all trying to win gold medals, and if you don't get a gold medal, you're nothing. There are actually a lot of people working together and contributing to the science - and the science is the important thing.

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.

I was married to Margaret Joan Howe in 1940. Although not a scientist herself she has contributed more to my work than anyone else by providing a peaceful and happy home.
