It may come as no surprise that theoretical physicist Hawking is extremely intelligent. Stephen Hawking told he would live only 2-3 years when diagnosed with motor neuron disease, Stephen Hawking age 69. Although Professor Hawking discounts the value of numerical IQ’s, he admitted that his own is likely very high (it has been suggested as 160 or more).
He also said that “People who boast about their IQ’s are losers”. Near the end of his term at Oxford and no doubt beginning to feel the effects of ALS, Hawking took a terrible fall down a staircase in the university hall. As a result, he temporarily lost his memory. He could not even remember his name.
After several hours of interrogation by his friends, he finally returned to normal but was worried about possible permanent brain damage. To be sure, he decided to take the Mensa test for individuals with superior intelligence. He was delighted to find that he passed with flying colours, scoring between 200 and 250!
