Physicist Stephen Hawking was today said to be “comfortable” after being taken to hospital by ambulance.
Professor Hawking, 67, who is based at Cambridge University, was admitted to Addenbrooke’s hospital in Cambridge on Monday.
University officials said Professor Hawking was “very ill” – he is thought to be suffering from a respiratory infection.
A university spokesman said today that Professor Hawking remained in hospital in a comfortable condition.
The academic suffers from motor neurone disease, is wheelchair bound and speaks with the aid of a voice synthesiser.
He developed the disease while a student in the 1960s and is one of the longest-surviving sufferers.
Professor Hawking is the Lucasian Professor of Mathematics at Cambridge and has been based at the university for more than 30 years.
He is one of the world’s leading cosmologists and is best known for his book 'A Brief History of Time'.
