This one should be very interesting, as not too many of those being talked about in these sections of this forum are still alive.

Stephen Hawking

Stephen Hawking was born January 8, 1942 in Oxford, England. From an early age, he showed a passion for science and the sky. At age 21, while studying cosmology at Cambridge, Hawking was diagnosed with Amyotrophic Lateral Sclerosis (ALS). Despite his debilitating illness, he has done ground-breaking work in physics and cosmology and his several books strive to make science accessible to everyone.

Early Life

The eldest of Frank and Isobel Hawking's four children, Stephen William Hawking was born on the 300th anniversary of the death ofGalileo, which has long been a source of pride for the noted physicist. Stephen was born into a family of thinkers. At a time when few women thought of going to college, the Scottish-born Isobel earned her way into Oxford University in the 1930s, making her one of the college's first female students. Frank Hawking, another Oxford graduate, was a respected medical researcher with a specialty in tropical diseases.

Stephen Hawking's birth came at an inopportune time for his parents, who didn't have much money. The political climate was also tense, as England was dealing with World War II and the onslaught of German bombs. In an effort to seek a safer place to have their first child, Frank moved his pregnant wife from their London home to Oxford. The Hawkings would go on to have two other children, Mary (1943) and Philippa (1947). A second son, Edward, was adopted in 1956.

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 kept bees in the basement and made fireworks in the greenhouse.

In 1950, Stephen's father took work as the head of the Division of Parasitology at the National Institute of Medical Research, and spent the winter months in Africa doing research. He wanted his eldest child to go into medicine, but from an early age Stephen showed a passion for science and the sky. That was evident to his mother, who, along with her children, often stretched out in the backyard on summer evenings to stare up at the stars. "Stephen always had a strong sense of wonder," she remembered. "And I could see that the stars would draw him."

Early in his academic life Stephen, while recognized as bright, was not an exceptional student. At one point in high school, his mother recalled, he was third from the bottom of his class. Instead, Stephen turned his mind loose on pursuits outside of school. He loved board games, and with a few close friends created new games of their own. At the age of 16 Stephen, along with several buddies, constructed a computer out of recycled parts for solving rudimentary mathematical equations.

He was also on the go a lot. "Always on the move," said a family friend. "Hardly ever still." With his sister Mary, Stephen, who loved to climb, devised different entry routes into the family home. He remained active even after he entered Oxford University at the age of 17. He loved to dance, and also took an interest in rowing, becoming one of the Oxford rowing team's coxswain. 


To his father's chagrin, Hawking finally said no to medicine, instead expressing a desire to study mathematics. But since Oxford didn't offer a mathematics degree, 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 and moved on to Cambridge University for a Ph.D. in cosmology.

ALS Diagnosis

While Stephen first began to notice problems with his physical health at Oxford—on occasion he would trip and fall, or slur his speech— he didn't look into the problem until 1963, during his first year at Cambridge. For the most part, Hawking had kept these minor symptoms to himself. But when his father took notice of the condition, he sent Stephen to see a doctor. For the next two weeks, the 21-year-old college student made his home at a medical clinic, where he underwent a series of tests.

"They took a muscle sample from my arm, stuck electrodes into me, and injected some radio opaque fluid into my spine, and watched it going up and down with X-rays, as they tilted the bed," he said. "After all that, they didn't tell me what I had, except that it was not multiple sclerosis, and that I was an a-typical case."

Eventually, however, doctors did inform the Hawkings about what was ailing their son: He was in the early stages of Amyotrophic Lateral Sclerosis (ALS or Lou Gehrig's disease). In a very simple sense, the nerves that controled his muscles were shutting down. Doctors gave him two and a half years to live.

It was devastating news for Stephen and his family. A few events, however, prevented him from becoming completely despondent. The first of these came while Hawking was still in the hospital. There, he shared a room with a boy suffering from leukemia. Relative to what his roommate was going through, Stephen reflected later, his situation seemed more tolerable. Not long after he was released from the hospital, Hawking had a dream that he was going to be executed. He said this dream made him realize that there were still things to do with his life.

But the most significant change in his life was the fact that he was in love. At a New Year's party in 1963, shortly before he had been diagnosed with ALS, Stephen Hawking met a young languages undergraduate named Jane Wilde. They were married in 1965.

In a sense, Hawking's disease helped him become the noted scientist he is today. Before the diagnosis, Stephen Hawking hadn't always focused on his studies. "I was bored with life before my illness," he said. "There had not seemed to be anything worth doing." 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.

Research on Black Holes

Groundbreaking findings from another young cosmologist, Roger Penrose, about the fate of stars and the creation of black holes tapped into Hawking's own fascination with how the universe began. This set him on a career course that reshaped the way the world thinks about black holes and the universe.

While physical control over his body diminished (he'd be forced to use a wheelchair by 1969), the effects of his disease started to slow down. In 1968, a year after the birth of his son Robert, Stephen Hawking became a member of the Institute of Astronomy in Cambridge.

The next few years were a fruitful time for Hawking. A daughter, Lucy, was born to Stephen and Jane in 1969 (a third child, Timothy, arrived 10 years later), while Hawking continued with his research. He then published his first book, the highly technical The Large Scale Structure of Space-Time (1975). He also teamed up with Penrose to expand upon his friend's earlier work.

In 1974, Stephen 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. Hawking Radiation was born.

The announcement sent shock waves of excitement through the scientific world, and put Hawking on a path that's been marked by honors, notoriety and distinguished titles. He was named a fellow of the Royal Society at the age of 32, and later earned the prestigiousAlbert Einstein Award. In 1975 he journeyed to Rome, where he was honored with the Pius XI Gold Medal for Science from Pope Paul VI.

Teaching stints followed, too. One was at Caltech at Pasadena, California, where Hawking served as visiting professor for a year. Another was at Gonville & Caius College in Cambridge, England. In 1979, Hawking found himself back at Cambridge University, where he was named to one of teaching's most renowned posts: the Lucasian Professor of Mathematics. Dating back to 1663, the position has been held by just 14 other people, including Sir Isaac Newton.

A Brief History of Time

Hawking's ever-expanding career was accompanied, however, by his ever-worsening physical state. By the mid-1970s, the Hawking family had taken in one of Stephen's graduate students to help manage his care and work. He could still feed himself and get out of bed, but virtually everything else required assistance. In addition, 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.

It also put in peril Hawking's ability to do his work. The predicament caught the attention of a California computer programmer, who had developed a speaking program that could be directed by head or eye movement. The invention allowed Hawking to select words on a computer screen that were then passed through a speech synthesizer. At the time of its introduction, Hawking, who still had use of his fingers, selected his words with a handheld clicker. Today, with virtually all control of his body gone, Hawking directs the program through a cheek muscle attached to a sensor. 


Through the program, and the help of assistants, Stephen Hawking has continued to write at a prolific rate. His work has included numerous scientific papers, of course, but also information for the non-scientific community. 

In 1988 Hawking, a recipient of the Commander of the Order of the British Empire, catapulted to international prominence with the publication of A Brief History of Time. The short, informative book became an account of cosmology for the masses. The work was an instant success, spending more than four years atop the London Sunday Times' best-seller list. Since its publication, it has sold more than 25 million copies worldwide and been translated into more than 40 languages. But it also wasn't as easy to understand as some had hoped. So in 2001, Hawking followed up his book with The Universe in a Nutshell, which offered a more illustrated guide to cosmology's big theories. Four years later, he authored the even more accessible A Briefer History of Time

Together the books, along with Hawking's own research and papers, articulate the physicist's personal search for science's Holy Grail: a single unifying theory that can combine cosmology (the study of the big) with quantum mechanics (the study of the small) to explain how the universe began. It's this kind of ambitious thinking that has allowed Hawking, who claims he can think in 11 dimensions, to lay out some big possibilities for humankind. He's convinced that time travel is possible, and that humans may indeed colonize other planets in the future.

Space Travel and Further Fame

Hawking's quest for big answers to big questions includes his own personal desire to travel into space. 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. Pictures of the freely floating physicist splashed across newspapers around the globe.

"The zero-G part was wonderful and the higher-G part was no problem. I could have gone on and on. Space, here I come!" he said.

If there is such a thing as a rock-star scientist, Stephen Hawking embodies it. His forays into popular culture have included guest appearances on The SimpsonsStar Trek: The Next Generation a comedy spoof with comedian Jim Carrey on Late Night with Conan O'Brien, and even a recorded voice-over on the Pink Floyd song "Keep Talking." In 1992, Oscar-winning filmmaker Errol Morris released a documentary about Hawking's life, aptly titled A Brief History of Time


Of course, as it is with any celebrity, fame has brought with it an interest in Stephen Hawking's personal life. And there have been some news-making events. In 1990, Stephen left his wife Jane for one of his nurses, Elaine Mason. The two were married in 1995, and the marriage put a strain on Hawking's relationship with his own children, who claimed Elaine closed off their father from them. In 2004, nurses looking after Hawking reported their suspicions to police that Elaine was physically abusing her husband. Hawking denied the allegations, and the police investigation was called off. 

In 2006, however, Hawking and Elaine filed for divorce. In the years since, the physicist has apparently grown closer with his family. He's reconciled with Jane, who has remarried, and published a science book for children with his daughter, Lucy. 

Hawking's health, of course, remains a constant concern—a worry that was heightened in early 2009 when he failed to appear at a conference in Arizona because of a chest infection. In April 2009, Hawking, who had already announced he was retiring after 30 years from the post of Lucasian Professor of Mathematics at Cambridge University, was rushed to the hospital for being what university officials described as "gravely ill." It was later announced that he was expected to make a full recovery. 

Hawking is scheduled to fly to the edge of space as one of Sir Richard Branson's pioneer space tourists. He said when asked about the subject in 2007, "Many people have asked me why I am taking this flight. I am doing it for many reasons... First of all, I believe that life on Earth is at an 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." 

In September 2010, Stephen Hawking spoke against the idea that God could have created the universe in his book The Grand Design. Hawking previously argued that belief in a creator could be compatible with modern scientific theories. His new work, however, concludes that the Big Bang was the inevitable consequence of the laws of physics and nothing more. "Because there is a law such as gravity, the universe can and will create itself from nothing," Hawking says. "Spontaneous creation is the reason there is something rather than nothing, why the universe exists, why we exist." 

The Grand Design is Hawking's first major publication in almost a decade. Within his new work, Hawking sets out to challenge Sir Isaac Newton's belief that the universe had to have been designed by God, simply because it could not have been born from chaos. "It is not necessary to invoke God to light the blue touch paper and set the universe going, " Hawking said.

Hawking made news in 2012 for two very different projects. It was revealed in early April that he had participated in a 2011 trial of a new headband-styled device called the iBrain. The device is designed to "read" the wearer's thoughts by picking up "waves of electrical brain signals," which are then interpreted by a special algorithm, according to an article in The New York Times. This device could be a revolutionary aid to Hawking and others with ALS.

Also around this time, Hawking showed off his humorous side on American television. He made a guest appearance on The Big Bang Theory, a popular comedy about a group of young, geeky scientists. Playing himself, Hawking brings the theoretical physicist Sheldon Cooper (Jim Parsons) back to Earth after finding an error in his work. Hawking earned kudos for this lighthearted effort.

To often considered Einsteinian....He is a brilliant scientist whose only fault is his ego. And the personal failure to realize that without consideration of other opinion and acknowledegemnt of  other individual beliefs systems in a fair and objective manner...he loses something of human value... and drops him for the genius category.
