The University of Louisville has received the largest single grant in school history. School administrators hope the funds will protect U of L from the faltering economy.The James Graham Brown Foundation is giving $20 million to U of L’s cancer center of the same name. University President James Ramsey says, despite the state of the economy, giving has not slowed down lately, but the funds will help the center continue its work if it does.“It’s a hard economic time for everybody. It’s hard to speculate," he says. "But certainly many investors are looking at their portfolios and their giving and what they can do. It’s a hard time, we understand that.”The money will be given to U of L in installments for the next five years.
