Hawking was the first to set out a theory ofÂ cosmologyÂ explained by a union of the general theory of relativity andÂ quantum mechanics. He was a vigorous supporter of theÂ many-worlds interpretationÂ of quantum mechanics.
Hawking was an HonoraryÂ Fellow of the Royal Society of ArtsÂ (FRSA), a lifetime member of theÂ Pontifical Academy of Sciences, and a recipient of theÂ Presidential Medal of Freedom, the highest civilian award in the United States. In 2002, Hawking was ranked number 25 in the BBCs poll of theÂ 100 Greatest Britons. He was theÂ Lucasian Professor of MathematicsÂ at the University of Cambridge between 1979 and 2009 and achieved commercial success with works ofÂ popular scienceÂ in which he discusses his own theories and cosmology in general; his bookÂ A Brief History of TimeÂ appeared on the BritishÂ Sunday TimesÂ best-seller list for a record-breaking 237 weeks.Hawking had a rare early-onset, slow-progressing form ofÂ amyotrophic lateral sclerosisÂ (ALS) that gradually paralysed him over the decades. At the time of his death, he was still able to communicate using a single cheek muscle attached to aÂ speech-generating device.Hawking died on 14 March 2018, at the age of 76.
