Stephen Hawking (1942 to 2018) was an English theoretical physicist and cosmologist whose work joined two great pillars of modern physics, general relativity and quantum mechanics, at the edge of a black hole. Born in Oxford and based for most of his career at the University of Cambridge, he became the Lucasian Professor of Mathematics, a chair once held by Isaac Newton, and kept it from 1979 to 2009.
He is remembered as much for how he worked as for what he found. Diagnosed at 21 with a form of motor neurone disease that doctors expected to kill him within a few years, he went on to research and publish for another five decades, most of that time unable to move or speak without help. His 1988 book A Brief History of Time carried cosmology to millions of general readers. He never received a Nobel Prize, because his central prediction has yet to be confirmed by experiment.
Stephen William Hawking was born in Oxford on 8 January 1942, to Frank Hawking, a medical researcher, and Isobel Hawking. The family later settled in St Albans, north of London. He read physics at University College, Oxford, taking a first-class degree, then moved to Trinity Hall, Cambridge, for graduate work in cosmology under Dennis Sciama.
In 1963, at the age of 21, Hawking was diagnosed with amyotrophic lateral sclerosis, a form of motor neurone disease that gradually destroys the nerves controlling voluntary movement. He was given only a few years to live. The illness advanced more slowly than expected, but it steadily took away his ability to walk, to write, and by the mid-1980s to speak. After a tracheotomy in 1985 he communicated through a voice synthesiser, operated first by hand and later by a single cheek muscle, producing the flat electronic voice that became his signature. He finished his 1966 doctoral thesis, "Properties of Expanding Universes," while the disease was already taking hold.
Hawking's early research, carried out with the mathematician Roger Penrose in the late 1960s, applied rigorous geometry to Einstein's general relativity. Their singularity theorems showed that under broad conditions a point of infinite density, a singularity, is unavoidable, both inside a black hole and at the start of an expanding universe. The work placed the Big Bang and black holes on firmer mathematical ground.
His best-known result came in 1974. Combining general relativity with quantum theory near a black hole's boundary, Hawking argued that black holes are not perfectly black. They should give off a faint thermal glow, now called Hawking radiation, slowly losing mass and, over immense spans of time, evaporating. The idea tied together gravity, quantum mechanics and thermodynamics, and it raised a hard question, still debated, about whether information that falls into a black hole is lost for good. The same year the Royal Society elected him a Fellow, at the unusually young age of 32.
Hawking radiation is widely seen as his deepest contribution, yet it has never been detected, because the glow from any real black hole is far too faint to measure with current instruments. That absence of experimental proof is the main reason he was never awarded a Nobel Prize, which is rarely given for theory alone.
From 1979 to 2009 Hawking held the Lucasian chair at Cambridge, and he continued to research and lecture there as a director of research until his death. Beyond his technical papers, he changed how the public met science. A Brief History of Time (1988) sold in the millions and made cosmology a subject of ordinary conversation, and later books and television appearances, including a turn in animated form, kept him in view.
He was appointed a Companion of Honour in 1989 and received the United States Presidential Medal of Freedom in 2009. He also became a prominent figure in disability advocacy, showing across half a century that a severe physical impairment need not end a working scientific life. Hawking died in Cambridge on 14 March 2018, at the age of 76. His ashes were interred in Westminster Abbey, between the graves of Isaac Newton and Charles Darwin.
Hawking's life is unusually well recorded, in his own papers, lectures and books, and that record is what lets each retelling be checked against fact rather than legend. Confinity keeps his story as one example of a life preserved in enough detail to be understood on its own terms.
