Dr. Stephen Hawking, the famed British theoretical physicist, science communicator, author and luminary, passed away in the early hours on Wednesday, March 14th. According to a statement from his family, the renowned scientist died peacefully in his home at Cambridge. He was 76 years old, and is survived by his first wife, Jane Wilde, and their three children – Lucy, Robert and Tim.

Dr. Hawking spent the past 50 years living with a terminal illness that slowly deprived him of his speech and the use of much of his body. He also leaves behind an unparalleled scientific legacy and millions of people worldwide who admired him for his genius, his sense of humor, and the way he sought to educate people on the importance of scientific research, space exploration, and disability awareness.

In 1963, when he was just 21 years old, Dr. Hawking was diagnosed with Amyotrophic Lateral Sclerosis (ALS, aka. Lou Gehrig’s disease), a degenerative form of motor neurone disease that would be with him for the rest of his life. At the time, he was told that he had only two years to live. This diagnosis caused Dr. Hawking to fall into a depression and lose interest in his studies, which he was pursuing at Cambridge University at the time.

However, his outlook soon changed as the disease progressed slower than his doctor’s originally though. It was also around this time that Hawking met his first wife, Jane Wilde. The two became engaged in October of 1964 and married on July 14th, 1966. Hawking would later say that his relationship with Wilde gave him “something to live for”.

The slow progression of the disease also allowed Dr. Hawking to embark on a career marked by brilliance, brashness, and original thinking. Among his many achievements, Dr. Hawing was the Lucasian Professor of Mathematics at the University of Cambridge, the Founder of the Center for Theoretical Cosmology, and served as the Sally Tsui Wong-Avery Director of Research at the Department of Applied Mathematics and Theoretical Physics until his passing.

During his lifetime, Dr. Hawking made invaluable contributions to the fields of theoretical physics and cosmology. These include his extensive work on gravitational singularity theorems (in collaboration with Roger Penrose), the theory that black holes emit radiation (often called Hawking Radiation), and a theory of cosmology that attempted to unify general relativity and quantum mechanics (aka. Theory of Everything).

His many accolades, honors and awards included being made an Honorary Fellow of the Royal Society of Arts (FRSA), a lifetime member of the Pontifical Academy of Sciences, and a recipient of the Presidential Medal of Freedom – the highest civilian award in the United States. In 2002, Hawking was ranked number 25 in the BBC’s poll of the 100 Greatest Britons.

The many books he penned include the best-selling A Brief History of Time, A Briefer History of Time, the essay collection Black Holes and Baby Universe, The Universe in a Nutshell, The Grand Design (which he co-authored with famed Caltech theoretical physicist and best-selling author Leonard Mlodinow) and his autobiography, My Brief History.

In 2007, Hawking and his daughter Lucy also published George’s Secret Key to the Universe, a children’s book designed to explain theoretical physics in an accessible fashion and featuring characters similar to those in the Hawking family. The book was followed by three sequels – George’s Cosmic Treasure Hunt (2009), George and the Big Bang (2011), George and the Unbreakable Code (2014).

In a statement by his three children, Lucy, Robert and Tim praised their father’s courage and persistence and honored how his genius and sense of humor inspired people all across the world:

“We are deeply saddened that our beloved father passed away today. He was a great scientist and an extraordinary man whose work and legacy will live on for many years… He once said, ‘It would not be much of a universe if it wasn’t home to the people you love.’ We will miss him forever.”

News of his passing was also met with a flurry of condolences by friends, colleagues, fans, and people whose lives he touched over the years. NASA tweeted the following early this morning, followed by a video of Dr. Hawking addressing the astronauts of the ISS in 2014:

Famed scientists and science communicator Neil DeGrasse Tyson also expressed his condolences, tweeting:

The cast of the Big Bang Theory, one of the many hit TV shows that Dr. Hawking made several appearances on, also offered their condolences and admiration:

The Motor Neurone Disease Association – of which Prof Hawking had been a patron since 2008- also expressed condolences on both their Facebook and twitter feeds. In addition, they reported that its website had crashed because of an influx of donations to the charity.

Despite having lived for five decades with this degenerative disease, Hawking had a very practical and courageous attitude about life. In 2011, he said in an interview with The Guardian that death was never far from his mind. “I have lived with the prospect of an early death for the last 49 years,” he said. “I’m not afraid of death, but I’m in no hurry to die. I have so much I want to do first.”

Hawking, a well-known atheist, was also clear on his thoughts on an afterlife. “I regard the brain as a computer which will stop working when its components fail,” he said. “There is no heaven or afterlife for broken down computers; that is a fairy story for people afraid of the dark.”

Dr. Hawking’s life and his contributions to science have been commemorated in many ways over the years. A film version of A Brief History of Time, directed by Errol Morris and produced by Steven Spielberg, premiered in 1992.  In 1997, a six-part television series Stephen Hawking’s Universe premiered on PBS, with a companion book also being released. In 2014, the story of his diagnosis and the impact it had on his young family was showcased in the Oscar-winning film The Theory of Everything.

Dr. Hawking has also been a major role model for people dealing with disabilities and degenerative illnesses and played an unparalleled role when it came to disability awareness and outreach. In 1999, he and eleven other luminaries joined with Rehabilitation International , an organization founded in 1922 “To advance the rights and inclusion of persons with disabilities across the world.”

In 2000, Dr. Hawking and his fellow luminaries signed the Charter for the Third Millennium on Disability, which called on governments around the world to prevent disabilities and protect disability rights. Throughout his life, Dr. Hawking also remained a committed educator  – personally supervising 39 successful PhD students – and lending his voice to scientific and humanitarian goals.

These include Breakthrough Initiatives, an effort to search for extraterrestrial intelligence (SETI) in the Universe, which Dr. Hawking helped launch in 2015. That same year, he also used his influence and celebrity status to promote the The Global Goals, a series of 17 goals adopted by the United Nations Sustainable Development Summit to end extreme poverty, social inequality, and fixing climate change over the course of the next 15 years.

To commemorate his life and legacy, a book of condolence has been opened at Gonville and Caius College in Cambridge, where Prof Hawking was a fellow. All around the world, there are outpourings of remembrance and support for his family from people who are mourning Dr. Hawking’s passing and celebrating his life and achievements.

As Neil DeGrasse Tyson said, the death of Dr. Hawking has left a vacuum in the scientific community, and in the hearts of people everywhere. However, his life and his many contributions shall be remembered for a long time to come!
