Stephen Hawking used to be an English theoretical physicist, cosmologist, writer, and Director of Research at the Centre for Theoretical Cosmology within the University of Cambridge. His scientific works included a collaboration with Roger Penrose on gravitational singularity theorems in the framework of general relativity and the theoretical prediction that black holes emit radiation, frequently known as Hawking radiation. Hawking used to be the first to set out a theory of cosmology explained by a union of the general theory of relativity and quantum mechanics. He used to be a vigorous supporter of the many-worlds interpretation of quantum mechanics. 

Hawking used to be a Fellow of the Royal Society (FRS), a life-time member of the Pontifical Academy of Sciences, and a recipient of the Presidential Medal of Freedom, the highest civilian award in america. In 2002, Hawking used to be ranked number 25 in the BBC’s poll of the 100 Greatest Britons. He used to be the Lucasian Professor of Mathematics at the University of Cambridge between 1979 and 2009 and achieved commercial success with works of popular science in which he discusses his own theories and cosmology in general. His book A Brief History of Time appeared on the British Sunday Times best seller list for a record-breaking 237 weeks. 

Hawking had a rare early-onset slow-progressing form of motor neurone disease (often referred to as amyotrophic lateral sclerosis, “ALS”, or Lou Gehrig’s disease) that gradually paralysed him over the decades. Even after the loss of his speech, he used to be still in a position to communicate through a speech-generating device, to begin with through use of a hand-held switch, and eventually by the use of a single cheek muscle.
