For 30 years, Jane Wilde says she remained in the shadows while her famous husband devoted himself to fame, success and thoughts of the universe.
She started caring for professor Stephen Hawking when he was diagnosed with Motor Nueron Disease at age 22 until they divorced.
Their marriage is the basis of the movie The Theory of Everything. The screenplay for the film was written by New Zealander Anthony McCarten and is based on Jane Wilde Hawking's memoir about her years with Stephen Hawking.
Now she's updated her original memoir in a new book called Travelling to Infinity: The True Story Behind the Theory of Everything that gives her account of their marriage, the painful divorce and recent reconciliation.
