What year was Stephen Hawking put in a wheelchair?

Answer 1

Here is what he said:
"In the end we got a mortgage from a building society, and my parents gave us the money to do it up. We lived there for another four years, but it became too difficult for me to manage the stairs. By this time, the College appreciated me rather more, and there was a different Bursar. They therefore offered us a ground floor flat in a house that they owned. This suited me very well, because it had large rooms and wide doors. It was sufficiently central that I could get to my University department, or the College, in my electric wheel chair. It was also nice for our three children, because it was surrounded by garden, which was looked after by the College gardeners.

Up to 1974, I was able to feed myself, and get in and out of bed. Jane managed to help me, and bring up the children, without outside help. However, things were getting more difficult, so we took to having one of my research students living with us. In return for free accommodation, and a lot of my attention, they helped me get up and go to bed. In 1980, we changed to a system of community and private nurses, who came in for an hour or two in the morning and evening. This lasted until I caught pneumonia in 1985. I had to have a tracheotomy operation. After this, I had to have 24 hour nursing care. This was made possible by grants from several foundations.

Before the operation, my speech had been getting more slurred, so that only a few people who knew me well, could understand me. But at least I could communicate. I wrote scientific papers by dictating to a secretary, and I gave seminars through an interpreter, who repeated my words more clearly. However, the tracheotomy operation removed my ability to speak altogether. For a time, the only way I could communicate was to spell out words letter by letter, by raising my eyebrows when someone pointed to the right letter on a spelling card. It is pretty difficult to carry on a conversation like that, let alone write a scientific paper. However, a computer expert in California, called Walt Woltosz, heard of my plight. He sent me a computer program he had written, called Equalizer. This allowed me to select words from a series of menus on the screen, by pressing a switch in my hand. The program could also be controlled by a switch, operated by head or eye movement. When I have built up what I want to say, I can send it to a speech synthesizer. At first, I just ran the Equalizer program on a desk top computer."
