Personal

Birth date: January 8, 1942

Birth place: Oxford, England

Birth name: Stephen William Hawking

Father: Frank Hawking, research biologist

Mother: Isobel Hawking

Marriages: Elaine Mason (1995-2006, divorced); Jane Wilde (1965-1991, divorced)

Children: with Jane Wilde: Timothy, Lucy and Robert

Other Facts

Hawking was born on the 300th anniversary of astronomer and physicist Galileo Galilei's death (January 8, 1642).

He was the 17th Lucasian Professor of Mathematics, an academic chair at Cambridge University. From 1669 to 1702, the position was held by Sir Isaac Newton.

Guest-starred, as himself, on "The Big Bang Theory," "Star Trek: The Next Generation" and "The Simpsons."

Visited all seven continents, including Antarctica.

Lou Gehrig's Disease (Amyotrophic Lateral Sclerosis or ALS), is usually fatal after three years. Hawking survived it for 55 years.

The disease left him paralyzed and completely dependent on others and/or technology for everything: bathing, dressing, eating, mobility and speech. He was able to move only a few fingers on one hand.

His speech synthesizer had an American accent.

Timeline

1963 - Is diagnosed with the motor neuron disease ALS.

1966 - Completes doctoral work in theoretical physics, submitting a thesis on black holes.

1970 - Combines the theory of relativity with quantum theory and finds that black holes emit radiation.
