LONDON, UK (X17online) - Harry Potter author J.K. Rowling has donated $15.4 million to a multiple sclerosis research center based at the University of Edinburgh in Scotland.

The center, called the Anne Rowling Regenerative Neurology Clinic, was created in honor of her mother who died of the disease back in 1990.

Rowling hopes the clinic will become "a world center for excellence in the field of regenerative neurology." Also studied at the center ... Alzheimer's and Parkinson's disease.

In a statement, Rowling says:

“Edinburgh has given me so very much that I have been looking for a way to give something meaningful back to the city for a long time. I cannot think of anything more important, or of more lasting value, than to help the university attract world-class minds in the field of neuroregeneration, to build on its long and illustrious history of medical research and, ultimately, to seek a cure for a very Scottish disease.”

Rowling also had the following to say about her mother:

“I know that she would rather have had her name on this clinic than on any statue, flower garden or commemorative plaque, so this donation is on her behalf, too; and in gratitude for everything she gave me in her far-too-short life."

Harry Potter books have sold over 400 million copies to date ... earning Rowling an estimated fortune worth $1 billion.
