Stephen Hawking was diagnosed with amyotrophic lateral sclerosis (ALS) at the age of 21, which gradually caused paralysis and made him unable to speak or move. Despite his disability, Hawking went on to become one of the most influential theoretical physicists of his time, using a speech-generating device to communicate and making significant contributions to our understanding of black holes and the nature of space and time.
