Hawking, famed for his work with black holes and relativity, died peacefully aged 76 at his home in Cambridge in the early hours of Wednesday (March 14).

IPC media and communications director Craig Spence told a press conference here that Parsons will be referring to Hawking in his speech at the Closing Ceremony, which is scheduled to take place on Sunday (March 18).

"Sometimes in society there is a wrong perception that if you have a disability it is a negative word and you can't do something, but Stephen Hawking turned that upside down and showed that, despite the fact he had Motor Neurone Disease, he could still excel in his field of work," Spence said.

"The obstacles put in front of him, he came up with solutions to those.

"He is an inspiration for all of us in the Paralympic Movement and Andrew will be paying tribute to him in his Closing Ceremony speech on Sunday."

Parsons has already paid tribute to Hawking in a statement, describing him as an "extraordinary man and a pioneer for all people with an impairment around the world".

In 2012, Hawking delivered an inspiring speech as part of the Opening Ceremony of the Paralympic Games in London.

He gave the world a global message of hope and optimism as he urged people to be curious and create a brave new and better world for everyone by challenging perceptions and stereotypes that limit the potential of humans.

Hawking wrote several popular science books, including A Brief History of Time.

At the age of just 22, he was given only a few years to live after being diagnosed with a rare form of Motor Neurone Disease.

It left him in a wheelchair and largely unable to speak apart from when doing so through a voice synthesiser.
