节俭的爱因斯坦

读到爱因斯坦节俭到近乎抠门的短文。
The mad hair came on the cheap.
Einstein's second wife was his cousin Elsa Loewenthal. Elsa could not persuade Einstein to pay for a barber so she would cut his hair herself. Waldow recalled: "When his hair was too long, when it was beyond the pale, Elsa would cut off his hair with scissors and he was willing to put up with it. As well as his disheveled hair, Elsa also trimmed the great scientist's moustache.
He made his shoes last.
Penny-pinching seems to have been a thing in the Einstein household - a seven-room apartment. Waldow, who was the housekeeper from 1927-1933, said that he was always short of cash and his wife was very penny pinching. He wore shoes with holes in them, even if they were no longer watertight. "He would wear them until it was no longer possible." She said his favourite footwear was sandals. No wonder he kept a sign up in his office in later life in Princeton that said: "Not everything that counts can be counted, and not everything that can be counted counts."
