Stephen Hawking was a theoretical physicist and cosmologist, widely considered as one of the greatest scientist of his time. In this brief biography we will look at Hawking's education and career ranging from his biographies to the popular books he has writtenStephen Hawking was a British scientist, professor and author who performed groundbreaking work in physics and cosmology, and whose books helped to make science accessible to everyone. 

EARLY LIFE AND CAREER

British Cosmologist  Stephen William Hawking was born in England on Jan 8, 1942 at Oxford, United Kingdom ------ 300 years to the day after the death of the Galileo Galilei.He was born in a family of Doctors. The Hawkings, as one close family friend described them, were an "eccentric" bunch. Dinner was often eaten in silence, each of the Hawkings intently reading a book. The family car was an old London taxi, and their home in St. Albans was a three-story fixer-upper that never quite got fixed. The Hawkings also housed bees in the basement

EDUCATION

Early in his academic life, Hawking, while recognized as bright, was not an exceptional student. During his first year at St. Albans School, he was third from the bottom of his class.But Hawking focused on pursuits outside of school; he loved board games, and he and a few close friends created new games of their own. During his teens, Hawking, along with several friends, constructed a computer out of recycled parts for solving rudimentary mathematical equations.

Hawking entered University College at the University of Oxford at the age of 17. Although he expressed a desire to study mathematics, Oxford didn't offer a degree in that specialty, so Hawking gravitated toward physics and, more specifically, cosmology.

By his own account, Hawking didn't put much time into his studies. He would later calculate that he averaged about an hour a day focusing on school. And yet he didn't really have to do much more than that. In 1962, he graduated with honors in natural science and went on to attend Trinity Hall at the University of Cambridge for a Ph.D. in cosmology.

In 1968, Hawking became a member of the Institute of Astronomy in Cambridge. The next few years were a fruitful time for Hawking and his research. In 1973, he published his first, highly-technical book, The Large Scale Structure of Space-Time. In 1979, Hawking found himself back at the University of Cambridge, where he was named to one of teaching's most renowned posts, dating back to 1663: the Lucasian Professor of Mathematics.

DISEASE

At the age of 21, Hawking was diagnosed with amyotrophic lateral sclerosis (ALS, Motor Neuron disease). In a very simple sense, the nerves that controlled his muscles were shutting down. At the time, doctors gave him two and a half years to live. With the sudden realization that he might not even live long enough to earn his Ph.D., Hawking poured himself into his work and research. 

SPEECH PROBLEM

His speech had become increasingly slurred, so that only those who knew him well could understand him. In 1985 he lost his voice for good following a tracheotomy. The resulting situation required 24-hour nursing care for the acclaimed physicist.

RESEARCH ON THE UNIVERSE

In 1974, Hawking's research turned him into a celebrity within the scientific world when he showed that black holes aren't the information vacuums that scientists had thought they were. 

In simple terms, Hawking demonstrated that matter, in the form of radiation, can escape the gravitational force of a collapsed star.

When Hawking’s radiation theory was born, the announcement sent shock waves of excitement through the scientific world. Hawking was named a fellow of the Royal Society at the age of 32, and later earned the prestigious Albert Einstein Award, among other honors. He also earned teaching stints at Caltech in Pasadena, California, where he served as visiting professor, and at Gonville and Caius College in Cambridge. 

In August 2015, Hawking appeared at a conference in Sweden to discuss new theories about black holes and the vexing "information paradox." Addressing the issue of what becomes of an object that enters a black hole, Hawking proposed that information about the physical state of the object is stored in 2D form within an outer boundary known as the "event horizon." Noting that black holes "are not the eternal prisons they were once thought," he left open the possibility that the information could be released into another universe.

DEATH

On March 14, 2018, Hawking finally died of ALS, the disease that was supposed to have killed him more than 50 years earlier. A family spokesman confirmed that the iconic scientist died at his home in Cambridge, England.
