“In my second year, after moving to the Medical School, I began the courses of Anatomy and Physiology. I had begun to see that I was interested in cells and their functions.”
“I set up a laboratory in the Department of Physiology in the Medical School in South Africa and begin to try to find a bacteriophage system which we might use to solve the genetic code.”
“I lived at home and I cycled every morning to the railway station to travel by train to Johannesburg followed by a walk to the University, carrying sandwiches for my lunch and returning in the evening the same way.”
