Biography of Stephen Hawking

Stephen Hawking, the world-famous theoretical physicist, was a British scientist and professor known for his work on black holes, relativity, and cosmology.

The author of popular science books like 'A Brief History of Time’ and ‘The Universe in a Nutshell’, as well as a series of children’s fiction books on the creation of the universe including ‘George and the Big Bang’, Hawking was applauded for helping to make science accessible to a wider audience, beyond scientists. That coupled with a good sense of humour made him one of the most recognisable scientists of modern times, and held in regard as one of the most remarkable theoretical physicists since Einstein.

In 1963, Hawking contracted amyotrophic lateral sclerosis (ALS) or motor neurone disease and was given three years to live. Yet he went on to Cambridge to become a researcher and professor. From 1979 to 2009 he held the post of Lucasian Professor at Cambridge, the chair held by Isaac Newton in 1663. Hawking received over a dozen honorary degrees and was awarded the CBE in 1982.

Over the course of his career, Hawking studied the basic laws governing the universe. He proposed that, since the universe boasts a beginning — the Big Bang — it likely will have an ending. Hawking later proposed that the universe itself has no boundary, never encountering a “wall” that would be described as the “end”.

In spite of being wheelchair-bound and dependent on a computerised voice system for communication, Hawking continued to combine family life with his research into theoretical physics, as well as enjoying life as a public figure with cult status, as it were, making guest appearances on TV shows including The Simpsons, Star Trek: The Next Generation, and The Big Bang Theory.

Hawking - who was born on the 300th anniversary of the death of Italian scientist Galileo - died on 14 March 2018 from the disease that was supposed to have killed him more than 50 years earlier. Interestingly, he died on the 139th anniversary of Einstein's birth.

1. Hawking's early life

Stephen Hawking was born on 8 January 1942, in Oxfordshire, England, where his mother had been sent for safety during the German bombings of London during World War II. His birthday was also the 300th anniversary of the death of Galileo — long a source of pride for the celebrated physicist.

His mother Isobel Hawking was an Oxford graduate and his father Frank Hawking was a medical researcher. Hawking was the eldest of their four children.

After Hawking's birth, the family reunited in London, where his father headed the division of parasitology at the National Institute for Medical Research. The family then moved to St Albans so that Frank Hawking could pursue medical research at the nearby Institute for Medical Research in Mill Hill.

The Hawkings family were said to be an “eccentric” bunch, as one close family friend described them. 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-storey fixer-upper that never quite got fixed. Hawking’s father wanted his eldest child to go into medicine, but at an early age, Hawking showed a passion for science and the sky.

Hawking attended school in St Albans, where he was an unexceptional student. His brilliance was much more apparent in his years at Oxford University, where he specialised in physics and graduated with first-class honours. In 1962, he continued his education at Cambridge University, pursuing a PhD in cosmology.

2. ALS Diagnosis

At age 21, a year after beginning his PhD, Stephen Hawking was diagnosed with ALS, and was given only three years to live.

Not long after he was released from the hospital following his diagnosis, Hawking had a dream that he was going to be executed. He said this dream made him realise that there were still things to do with his life.

Just before his diagnosis, Hawking met Jane Wilde, and the two were married in 1965. The couple gave birth to a son, Robert, in 1967, and a daughter, Lucy, in 1970. A third child, Timothy, arrived in 1979.

Hawking's disease helped turn him into the noted scientist he became. Before the diagnosis, Hawking hadn't always focused on his studies as he admitted:

"Before my condition was diagnosed, I had been very bored with life. There had not seemed to be anything worth doing."

With the realisation that he might not even live long enough to earn his PhD, Hawking poured himself into his work and research.

As Hawking’s disease progressed, he became less mobile and began using a wheelchair. Hawking eventually lost his ability to speak, so he utilised a device capable of translating his cheek movements to speak in a digitised voice. While Hawking was a celebrated physicist, he became well respected for his ability to accomplish so much while suffering the debilitating affects caused by ALS.

3. Scientific Triumphs

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.

Hawking demonstrated that matter, in the form of radiation, can escape the gravitational force of a collapsed star. Working with fellow cosmologist Roger Penrose, he demonstrated that Albert Einstein's Theory of General Relativity suggests that space and time began at the birth of the universe and ends within black holes, which implies that Einstein's theory and quantum theory must be united.

Using the two theories together, Hawking also determined that black holes are not totally dark but instead emit radiation. He predicted that, following the Big Bang, black holes as tiny as protons were created, governed by both general relativity and quantum mechanics.

That same year, Hawking was inducted into the Royal Society, a worldwide fellowship of scientists. In 1979, he was appointed Lucasian Professor of Mathematics at Cambridge, the most famous academic chair in the world (the second holder was Sir Isaac Newton, also a member of the Royal Society), among other honours. He also earned teaching stints at Caltech in California, where he served as visiting professor, and at Gonville and Caius College in Cambridge.

In 2014, Hawking revised his earlier theory, even writing that "there are no black holes" — at least, in the way that cosmologists traditionally understand them. His theory removed the existence of an "event horizon", the point where nothing can escape. Instead, he proposed that there would be an "apparent horizon" that would alter according to quantum changes within the black hole.

In 2007, at the age of 65, Hawking made an important step toward space travel. While visiting the Kennedy Space Center in Florida, he was given the opportunity to experience an environment without gravity.

Over the course of two hours over the Atlantic, Hawking, a passenger on a modified Boeing 727, was freed from his wheelchair to experience bursts of weightlessness. He recalled: "The zero-G part was wonderful, and the high-G part was no problem. I could have gone on and on. Space, here I come!"

In a 2007 statement, Hawking declared:

"Life on Earth is at the ever-increasing risk of being wiped out by a disaster, such as sudden global warming, nuclear war, a genetically engineered virus or other dangers. I think the human race has no future if it doesn't go into space. I therefore want to encourage public interest in space."

Hawking was scheduled to fly to the edge of space as one of Sir Richard Branson's pioneer space tourists.

Over the years, Hawking wrote and co-wrote a total of 15 books. They included the 1988 best seller 'A Brief History of Time' which offered a simple explanation of cosmology, and offered an overview of space and time, the existence of God and the future.

Hawking went on to write other non-fiction books aimed at non-scientists. These include ‘A Briefer History of Time’, ‘The Universe in a Nutshell’, ‘The Grand Design’, and ‘On the Shoulders of Giants’.

He and his daughter, Lucy Hawking, also created a fictional series of books for school children on the creation of the universe, including ‘George and the Big Bang’.

Over the years, Hawking became somewhat of a celebrity scientist and made several guest appearances on TV shoes including playing a hologram of himself on Star Trek: The Next Generation and a cameo on the comedy hit Big Bang Theory. He also made appearances on the The Simpsons and Futurama.

In 2014, a movie based on Hawking's life starring British actor Eddie Redmayne was released. 'The Theory of Everything' charted the story of Hawking’s early life and school days, his courtship and marriage to Wilde, as well as the progression of his crippling disease and his scientific triumphs.

The film drew praise from Hawking who admitted the film made him reflect on his own life. In a Facebook post he said:

"Although I'm severely disabled, I have been successful in my scientific work,"

Stephen Hawking died in his home in Cambridge, England on 14 March 2018. He was 76. His ashes were placed in London’s Westminster Abbey between the final resting places of Sir Isaac Newton and Charles Darwin.

4. Hawking's legacy

Stephen Hawking made huge contributions as a scientist and science communicator. His theories and research leave questions for the next generation of scientists.

The Stephen Hawking Medal for Science Communication, an award created for individuals who promote public awareness of science, is one of many that honours the legendary scientist.

Earlier this year, The Royal Mint released a new 50p coin in honour of Hawking’s life and work. The coin’s eye-catching design features Hawking’s name and his mathematical formula for black hole thermodynamics seemingly caught in a black hole vortex. The rare coin is one of several released by The Royal Mint to commemorate top scientists.

Aside from his scientific work, Hawking was an inspiration to many for his courage and strength in overcoming obstacles.
