About Hawking-

His book A Brief History of Time appeared on the British Sunday Times best-seller list for a record-breaking 237 weeks.
In 2002, Hawking was ranked number 25 in the BBC's poll of the 100 Greatest Britons.
Hawking had a rare early-onset slow-progressing form of motor neurone disease (also known as amyotrophic lateral sclerosis "ALS" or Lou Gehrig's disease) that gradually paralyzed him over the decades.
in collaboration with Penrose, Hawking extended the singularity theorem concepts first explored in his doctoral thesis.
In 1970 they published a proof that if the universe obeys the general theory of relativity and fits any of the models of physical cosmology developed by Alexander Friedmann, then it must have begun as a singularity.
In 1970, Hawking postulated what became known as the second law of black hole dynamics, that the event horizon of a black hole can never get smaller.
With James M. Bardeen and Brandon Carter, he proposed the four laws of black hole mechanics, drawing an analogy with thermodynamics.
His essay titled "Black Holes" won the Gravity Research Foundation Award in January 1971. Hawking's first book, The Large Scale Structure of Space-Time, written with George Ellis, was published in 1973.
showed that black holes emit radiation, known today as Hawking radiation, which may continue until they exhaust their energy and evaporate. Initially, Hawking radiation was controversial. By the late 1970s and following the publication of further research, the discovery was widely accepted as a significant breakthrough in theoretical physics.
At the time, he was one of the youngest scientists to become a Fellow of the Royal Society(FRS).
Hawking was born on the 300th anniversary of Galileo's death and died on the 139th anniversary of Einstein's birth.
Black Hole discovery dedication: In March 2018, it was announced that two Russian astronomers who discovered GRB180316A, a newborn black hole in the Ophiuchus constellation on 16 March 2018, had dedicated their find to Stephen Hawking, having discovered it two days after his death.
