No one could have enjoyed himself more, either in creative work or the honors it brought him. He worked hard, but with immense gusto; he got pleasure not only from the high moments, but also from the hours of what to others would be drudgery, sitting in the dark counting the alpha particle scintillations on the screen. His insight was direct, his intuition, with one curious exception, infallible. No scientist has made fewer mistakes. In the corpus of his published work, one of the largest in scientific history, there was nothing he had to correct afterwards. By thirty he had already set going the science of nuclear physics — single-handed, as a professor on five hundred pounds a year, in the isolation of late-Victorian Montreal. By forty, now in Manchester, he had found the structure of the atom — on which all modern nuclear physics depends.

It was an astonishing career, creatively active until the month he died. He was born very poor, as I have said. New Zealand was, in the 1880s, the most remote of provinces, but he managed to get a good education; enough of the old Scottish tradition had percolated there, and he won all the prizes. He was as original as Einstein, but unlike Einstein he did not revolt against formal instruction; he was top in classics as well as in everything else. He started research — on the subject of wireless waves — with equipment such as one might rustle up today in an African laboratory. That did not deter him: “I could do research at the North Pole,” he once proclaimed, and it was true. Then he was awarded one of the 1851 overseas scholarships (which later brought to England Florey, Oliphant, Philip Bowden, a whole series of gifted Antipodeans). In fact, he got the scholarship only because another man, placed above him, chose to get married: with the curious humility that was interwoven with his boastfulness, he was grateful all of his life. There was a proposal, when he was Lord Rutherford, President of the Royal Society, the greatest of living experimental scientists, to cut down these scholarships. Rutherford was on the committee. He was too upset to speak: at last he blurted out:

He was too upset to speak: at last he blurted out: <i>&ldquo;If it had not been for them, I shouldn't have been.&rdquo;</i> That was nonsense. Nothing could have stopped him. He brought his wireless work to Cambridge, anticipated Marconi, and then dropped it because he saw a field — radioactivity — more scientifically interesting. If he had pushed on with wireless, incidentally, he couldn't have avoided becoming rich. But for that he never had time to spare. He provided for his wife and daughter, they lived in comfortable middle-class houses — and that was all. His work led directly to the atomic energy industry spending, within ten years of his death, thousands of millions of pounds. He himself never earned, or wanted to earn, more than a professor's salary — about £1,600 a year at the Cavendish in the thirties. In his will he left precisely the value of his Nobel Prize, then worth £7,000. Of the people I am writing about, he died much the poorest: even G. H. Hardy, who by Rutherford's side looked so ascetic and unworldly, happened not to be above taking an interest in his investments.

As soon as Rutherford got on to radioactivity, he was set on his life's work. His ideas were simple, rugged, material: he kept them so. He thought of atoms as though they were tennis balls. He discovered particles smaller than atoms, and discovered how they moved or bounced. Sometimes the particles bounced the wrong way. Then he inspected the facts and made a new but always simple picture. In that way he moved, as certainly as a sleepwalker, from unstable radioactive atoms to the discovery of the nucleus and the structure of the atom.

He had a touch of genius: in those days, before life sobered him, he had also a touch of the inspired Russian clown. He loved his own country, but he distinctly enjoyed backing both horses, working in Cambridge and taking his holidays in the Caucasus. He once asked a friend of mine if a foreigner could become an English peer; we strongly suspected that his ideal career would see him established simultaneously in the Soviet Academy of Sciences and as Rutherford's successor in the House of Lords.

At that time Kapitsa attracted a good deal of envy, partly because he could do anything with Rutherford. He called Rutherford &ldquo;the Crocodile,&rdquo; explaining the crocodile means &ldquo;father&rdquo; in Russian, which it doesn't, quite: he had Eric Gill carve a crocodile on his new laboratory. He flattered Rutherford outrageously, and Rutherford loved it. Kapitsa could be as impertinent as a Dostoevskian comedian: but he had great daring and scientific insight. He established the club named after him (which again inspired some envy): it met every Tuesday night, in Kapitsa's rooms in Trinity, and was deliberately kept small, about thirty, apparently because Kapitsa wanted to irritate people doing physical subjects he disapproved of. We used to drink large cups of milky coffee immediately after hall (living was fairly simple, and surprisingly non-alcoholic, in scientific Cambridge), and someone gave a talk — often a dramatic one, like Chadwick*s on the neutron. Several of the major discoveries of the thirties were first heard in confidence in that room. I don't think that the confidence was ever broken.

I myself enjoyed the one tiny scientific triumph of my life there. At the time Kapitsa barely tolerated me, since I did spectroscopy, a subject he thought fit only for bank clerks: in fact I had never discovered why he let me join. One night I offered to give a paper outside my own subject, on nuclear spin, in which I had been getting interested: I didn't know much about it, but I reckoned that most of the Cavendish knew less. The offer was unenthusiastically accepted. I duly gave the paper. Kapitsa looked at me with his large blue eyes, with a somewhat unflattering astonishment, as at a person of low intelligence who had contrived inadvertently to say something interesting. He turned to Chadwick, and said incredulously, &ldquo;Jimmy, I believe there is something in this.&rdquo;
