Stephen Hawking was a English theoretical physicist and cosmologist. He died recently.
He was quite famous I believe, do you know what disease he was afflicted by?
He was born in 1942 and held academic positions at Cambridge. He suffered from motor neuron disease.
Oh interesting, do you know if his motor neuron disease had a more formal name? I swear I've heard it referred to by something else.
There are several names given to it, like MND. Its origins are not yet known.
