“Cavendish is a book in himself. Born into a life of sumptuous privilege- his grandfathers were dukes, respectively, of Devonshire and Kent- he was the most gifted English scientist of his age, but also the strangest. He suffered, in the words of one of his few biographers, from shyness to a "degree bordering on disease." Any human contact was for him a source of the deepest discomfort. Once he opened his door to find an Austrian admirer, freshly arrived from Vienna, on the front step. Excitedly the Austrian began to babble out praise. For a few moments Cavendish received the compliments as if they were blows from a blunt object and then, unable to take any more, fled down the path and out the gate, leaving the front door wide open. It was some hours before he could be coaxed back to the property. Even his housekeeper communicated with him by letter.Although he did sometimes venture into society- he was particularly devoted to the weekly scientific soirees of the great naturalist Sir Joseph Banks- it was always made clear to the other guests that Cavendish was on no account to be approached or even looked at. Those who sought his views were advised to wander into his vicinity as if by accident and to "talk as it were into vacancy." If their remarks were scientifically worthy they might receive a mumbled reply, but more often than not they would hear a peeved squeak (his voice appears to have been high pitched) and turn to find an actual vacancy and the sight of Cavendish fleeing for a more peaceful corner.”

“On the morning of our second day, we were strolling down the Champs-Elysées when a bird shit on his head. ‘Did you know a bird’s shit on your head?’ I asked a block or two later.Instinctively Katz put a hand to his head, looked at it in horror – he was always something of a sissy where excrement was concerned; I once saw him running through Greenwood Park in Des Moines like the figure in Edvard Munch’s ‘The Scream’ just because he had inadvertently probed some dog shit with the tip of his finger – and with only a mumbled ‘Wait here’ walked with ramrod stiffness in the direction of our hotel. When he reappeared twenty minutes later he smelled overpoweringly of Brut aftershave and his hair was plastered down like a third-rate Spanish gigolo’s, but he appeared to have regained his composure. ‘I’m ready now,’ he announced.Almost immediately another bird shit on his head. Only this time it really shit. I don’t want to get too graphic, in case you’re snacking or anything, but if you can imagine a pot of yoghurt upended onto his scalp, I think you’ll get the picture. ‘Gosh, Steve, that was one sick bird,’ I observed helpfully.Katz was literally speechless. Without a word he turned and walked stiffly back to the hotel, ignoring the turning heads of passers-by. He was gone for nearly an hour. When at last he returned, he was wearing a windcheater with the hood up. ‘Just don’t say a word,’ he warned me and strode past. He never really warmed to Paris after that.”

“Perhaps the most irrational fashion act of all was the male habit for 150 years of wearing wigs. Samuel Pepys, as with so many things, was in the vanguard, noting with some apprehension the purchase of a wig in 1663 when wigs were not yet common. It was such a novelty that he feared people would laugh at him in church; he was greatly relieved, and a little proud, to find that they did not. He also worried, not unreasonably, that the hair of wigs might come from plague victims. Perhaps nothing says more about the power of fashion than that Pepys continued wearing wigs even while wondering if they might kill him.”

“I turned to my own bunk and examined it with a kind of appalled fascination. If the mattress stains were anything to go by, a previous user had not so much suffered from incontinence as rejoiced in it. He had evidently included the pillow in his celebrations.”

“When the poet Paul Valery once asked Albert Einstein if he kept a notebook to record his ideas, Einstein looked at him with mild but genuine surprise. "Oh, that's not necessary," he replied . "It's so seldom I have one.”

“Joseph Stalin was a great man; few other men of the 20th century approach his stature. He was simple, calm and courageous. He seldom lost his poise; pondered his problems slowly, made his decisions clearly and firmly; never yielded to ostentation nor coyly refrained from holding his rightful place with dignity. He was the son of a serf but stood calmly before the great without hesitation or nerves. But also - and this was the highest proof of his greatness - he knew the common man, felt his problems, followed his fate.Stalin was not a man of conventional learning; he was much more than that: he was a man who thought deeply, read understandingly and listened to wisdom, no matter whence it came. He was attacked and slandered as few men of power have been; yet he seldom lost his courtesy and balance; nor did he let attack drive him from his convictions nor induce him to surrender positions which he knew were correct.”

“It took Pueblo a few seconds to take in his surroundings. The first thing he realised was that he felt bruised all over; the second was that his clothes were waterlogged, even more than before, from the quicksand; and the third, was that he had landed on his front and was lying on a large, uncomfortable stone.No, wait… In his disoriented state, he shifted his weight. The stone didn't move. He was lying on his own fucking erection.”
