I did help to set up an undergraduate course in medicinal chemistry and made progress in modelling and analysing pharmacological activity at the tissue level, my new passion.

We paid off our debts, we learned some, made friends and returned in 1950 with a larger view of life. I had, however, no home, no income of any kind and no prospects whatsoever.

Peer reviewers go for orthodoxy ... Many of the great 19th-century discoveries were made by men who had independent wealth-Charles Darwin is the prototype. They trusted themselves.

I met Hilary Vaughan at a Student Ball in 1944 and we married in the summer of 1946, as soon as I graduated.

I learnt, for the first time, the joys of substituting hard, disciplined study for the indulgence of day-dreaming.

I wish I had my beta-blockers handy.

Apart from two periods of intense study, of music between the ages of 12 and 14 and of mathematics between the ages of 14 and 16, I coasted, daydreaming, through most of my school years.
