The Columbia University professor who wrote "A Beautiful Mind" has filed suit against the school over nearly $1 million that she says she is owed.

According to a summons filed in state Supreme Court in Manhattan, Sylvia Nasar says Columbia owes her $923,000 dating back to September 1998 from an endowment grant from the John S. and James L. Knight Foundation.

The summons was filed on January 7.

Columbia declined to comment.

Nasar is the John S. and James L. Knight Professor of Business Journalism at Columbia.

She has written for numerous publications including The New York Times and The New Yorker magazine.

"A Beautiful Mind" tells the life story of economist John Nash.
