Professor Stephen Hawking's famous office at Cambridge University should be preserved as a "teaching tool", according to his daughter.
On Good Morning Britain today (June 13), Lucy Hawking gave her first television interview since the scientist's death in March, aged 76.
In it, she paid tribute to her father's determination, academic brilliance - and fierce fondness for mischief.
She said that Professor Hawking had refused to let motor neurone disease "define him" and that he "bore his challenges with enormous dignity".
She also called for his world-famous office at Cambridge University's Gonville and Caius College to be preserved for others to learn from.
