WASHINGTON — Underwriting major performances over the next decade, Virginia businesswoman and arts philanthropist Catherine B. Reynolds has donated to the Kennedy Center its largest programming-related gift ever: $10 million.

No restrictions were placed on the largesse, which will establish the Catherine B. Reynolds Series for Artistic Excellence. The inaugural perf will be a May joint appearance of the Bolshoi Ballet and Bolshoi Opera.

Kennedy Center president Kaiser called the Reynolds gift a programmer’s dream, one that “gives us the opportunity to choose projects of the highest quality from a broad spectrum of art forms.” Future projects are undetermined.

It was announced during the Center’s busiest and highest-profile week of the year, featuring the Kennedy Center Honors festivities and the National Symphony Orchestra ball. The two fund-raising events drew over $2 million and $1 million, respectively. Reynolds and her husband, Wayne, co-chaired the NSO event and underwrote its costs.
