Donald Bren and four other Newport Beach philanthropists were honored for their giving at the National Philanthropy Day awards luncheon in Anaheim on Wednesday.

Bren, the chairman of the Irvine Co., has given more than $60 million to UC Irvine, both privately and through his Donald Bren Foundation. His other giving has benefitted K-12 education and conservation groups.

Marion Knott has donated to Orange County arts, science and healthcare organizations, including $8 million to Chapman University. Phil and Mary Lyons have given financial support and many volunteer hours to Orange County arts programs, including the Pacific Symphony. Jerri Rosen founded Working Wardrobes, a nonprofit that helps unemployed women with professional "wardrobing" and career development services.
