Stephen Hawking

Verified Timeline

Lore & Background

Hawking was born in Oxford into a family of physicians. In 1959, at age 17, he began his university education at University College, Oxford, where he received a first-class BA degree in physics. In 1962, he began graduate work at Trinity Hall, Cambridge, obtaining his PhD in 1966 in applied mathematics and theoretical physics, specialising in general relativity and cosmology. In 1963, at age 21, Hawking was diagnosed with an early-onset slow-progressing form of motor neurone disease that gradually paralysed him over decades. After losing his speech, he communicated through a speech-generating device, initially using a handheld switch and eventually a single cheek muscle. Hawking's 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, often called Hawking radiation. Initially controversial, by the late 1970s and following further research, the discovery was widely accepted as a major breakthrough. He was the first to set out a theory of cosmology explained by a union of general relativity and quantum mechanics, supported the many-worlds interpretation of quantum mechanics, and introduced the notion of a micro black hole. He achieved commercial success with several works of popular science, most notably A Brief History of Time, which appeared on the Sunday Times bestseller list for a record-breaking 237 weeks.

Reader's Guide

Stephen Hawking's significance lies in his groundbreaking theoretical work that reshaped modern cosmology and our understanding of black holes. His prediction of Hawking radiation, which combined general relativity with quantum mechanics, demonstrated that black holes are not entirely black but emit radiation, a concept that was initially controversial but later widely accepted as a major breakthrough. His collaboration with Roger Penrose on gravitational singularity theorems provided key insights into the nature of spacetime. Hawking also popularized complex scientific ideas through books like A Brief History of Time, making cosmology accessible to a broad audience. Despite being diagnosed with motor neurone disease at age 21 and gradually becoming paralyzed, he continued his research and communication for over 50 years, becoming a symbol of intellectual perseverance. His legacy includes his role as Lucasian Professor of Mathematics at Cambridge, his membership in the Royal Society and the Pontifical Academy of Sciences, and his receipt of the Presidential Medal of Freedom.

Did You Know?

• At age 21, Hawking was diagnosed with an early-onset slow-progressing form of motor neurone disease and given only two years to live, but he lived for more than 50 years after the diagnosis.
• After losing his speech, Hawking communicated using a speech-generating device, initially with a handheld switch and eventually by using a single cheek muscle.
• His book A Brief History of Time spent a record-breaking 237 weeks on the Sunday Times bestseller list.
• In 2002, Hawking was ranked number 25 in the BBC's poll of the 100 Greatest Britons.

Academic Career & Scientific Breakthroughs

Stephen Hawking's academic trajectory placed him at the very apex of theoretical physics. After earning his doctorate in 1966 from Trinity Hall, Cambridge, with a specialisation in general relativity and cosmology, he went on to hold the Lucasian Professorship of Mathematics between 1979 and 2009—a chair long regarded as among the most distinguished in global academia. He also served as director of research at Cambridge's Centre for Theoretical Cosmology. His most celebrated contributions include a joint programme with Roger Penrose establishing gravitational singularity theorems within general relativity, and the bold theoretical prediction that black holes are not entirely black but instead emit a faint thermal glow now universally known as Hawking radiation. That idea was fiercely debated when first proposed, yet by the late 1970s, bolstered by subsequent research, the physics community had embraced it as a landmark advance. Hawking was also the first to articulate a unified cosmological framework weaving together general relativity and quantum mechanics, championed the many-worlds interpretation of quantum theory, and introduced the concept of a micro black hole.

The Diagnosis & Defying the Odds

In 1963, at just twenty-one years old, Hawking received a diagnosis of an early-onset, slow-progressing form of motor neurone disease. The prognosis was grim: over the following decades the condition would steadily rob him of his physical abilities, ultimately leaving him almost entirely paralysed. When he lost the ability to speak, he turned to a speech-generating device to make himself understood. At first he operated it with a handheld switch; later, as his condition advanced, he relied on the movement of a single cheek muscle to trigger each word. Remarkably, he continued to produce groundbreaking theoretical work throughout this period, holding the Lucasian chair for three decades and remaining active in public life. He died on 14 March 2018 at the age of seventy-six, having lived more than fifty years beyond the date of his diagnosis—a span that far exceeded the expectations his doctors had offered him as a young graduate student.

Public Legacy & Recognition

Beyond the lecture hall, Hawking became one of the most recognisable scientists in modern history, largely thanks to his popular-science writing. His book A Brief History of Time, in which he explained his own theories and the broader story of cosmology to a general audience, spent a record-breaking 237 consecutive weeks on the Sunday Times bestseller list—a feat that underscored how widely his ideas had penetrated public consciousness. His institutional honours were equally impressive: he was elected a Fellow of the Royal Society, appointed a lifetime member of the Pontifical Academy of Sciences, and received the Presidential Medal of Freedom, the highest civilian distinction the United States can bestow. In 2002, a BBC poll ranking the 100 Greatest Britons placed him at number twenty-five.

Formative Years & Family Influence

Hawking was born in Oxford in 1942 into a household steeped in medicine. His mother, Isobel, came from a line of physicians in Glasgow, while his father, Frank, was a medical researcher focused on tropical diseases. Growing up in St Albans, where the family was described as highly intelligent and somewhat eccentric, young Stephen absorbed a culture of quiet intellectualism; meals often consisted of each member silently absorbed in a book. His father's example proved decisive: Hawking later recalled that he modelled himself on Frank as a scientific researcher, though he gravitated toward physics rather than medicine because the latter felt "too inexact and descriptive." At school, nicknamed "Einstein," he was not an early academic standout, but a mathematics teacher named Dikran Tahta sparked his interest in the subject. Together they assembled a rudimentary computer from clock parts and a discarded telephone switchboard, and Hawking built a record player from cheap spare components—a project he pitched to his frugal, Yorkshire-born father as a cost-saving exercise. These hands-on experiments foreshadowed a lifetime of turning abstract ideas into tangible understanding.
