The Motor Neurone Disease Association says it has had an influx of donations this morning following the death of Professor Stephen Hawking.
The charity, based in Northampton, says it's had so much traffic over the past couple of hours the website has now crashed. Professor Hawking became Patron of MND Association in 2008.

Prof Hawking survived for around half a century after being diagnosed with motor neurone disease (MND), despite being told he had just years to live when he was diagnosed
"All of us at the MND Association have been extremely saddened by the news of Professor Hawking's passing. Through so many years in the public eye he did a huge amount to raise awareness of motor neurone disease, yet he never allowed himself to be defined by his illness. His approach to life with MND is an example to all of us."
The disease kills a third of people within a year and more than half within two years of diagnosis. Yet Prof Hawking was diagnosed with the condition in his early 20s and lived until he was 76.
The condition is fatal, and usually progresses rapidly, affecting the brain and spinal cord.
The MND Association states that the condition affects everyone differently - not all symptoms will affect everyone and symptoms progress at varying speeds.
It affects around 5,000 people in the UK. There is no cure for MND and there is not a clear answer about what causes the condition.
A public ballot has opened for tickets to Professor Stephen Hawking's thanksgiving service next month.
A charity helping the hungry in Cambridge was able to put on an extra-special Easter lunch - thanks to Stephen Hawking.
Film star Eddie Redmayne will give a reading at the funeral of renowned physicist Stephen Hawking this afternoon (Saturday).
