A legend in the science field for his well known 'Hawking Radiation' which helped our knowledge in Science to increase to a large extent.
This man broke science by living for 76 years having amyotrophic lateral sclerosis, a disease which causes a man to die within 5-10 years. But this man had it for a whopping 55 years.
A wonderful man with a great sense of humor(not kidding).
We're lucky to have had you, Stephen Hawking!
Note that he also died on Pi Day
