Stephen William Hawking was born on January 8, 1942, in Oxford, England — exactly three hundred years after the death of Galileo Galilei, a coincidence he enjoyed noting. His father Frank was a tropical medicine researcher and his mother Isobel a medical secretary. Hawking was a curious but unremarkable student at St Albans School, gaining the nickname 'Einstein' among classmates less for demonstrated brilliance than for the conviction that he possessed some unusual inner resource. At Oxford he studied physics with what his tutors described as effortless ability and minimal work, graduating with first-class honors in 1962 before moving to Cambridge to pursue cosmology under Dennis Sciama.
At Cambridge, Hawking began experiencing the symptoms of motor neurone disease — ALS — that would progressively paralyze him over the next decade. Diagnosed at twenty-one, he was initially given two years to live. The diagnosis provoked a transformation: where he had been directionless and unmotivated, he became intensely focused, pouring his intellectual energy into theoretical physics with a concentration that was perhaps only possible once ordinary physical life had been stripped away. His doctoral work with Roger Penrose demonstrated that if general relativity was correct, there must have been a singularity at the beginning of the universe — the mathematical foundation of the Big Bang theory.
Hawking's later theoretical work showed that black holes emit radiation — now known as Hawking radiation — a result that connected quantum mechanics and general relativity in a way that no one had previously achieved and that most physicists regard as the most important theoretical result of the second half of the twentieth century. His popular book A Brief History of Time (1988) spent a record-breaking 237 weeks on the Sunday Times bestseller list and sold over 10 million copies, making him the most famous scientist in the world. He communicated through a computerized speech synthesizer after losing his voice entirely in 1985, producing a distinctive synthetic voice that became instantly recognizable.
Hawking died on March 14, 2018 — Pi Day and Albert Einstein's birthday — having survived his diagnosis by 55 years. His life is one of the most extraordinary demonstrations of INTP resilience and intellectual independence: the mind that kept thinking with complete rigor and originality as the body that contained it progressively failed, sustained by the same quality that defines the INTP at its best — the absolute priority of understanding as an end in itself, valuable independently of any physical capacity or circumstance.
