Jimmy and Rosalynn Carter on Tuesday night mourned the death of former first lady Barbara Bush, calling attention to her generous spirit, gregarious nature and devotion to family.

“Rosalynn and I are saddened by the death of Barbara Bush,” the couple said In a statement released by the Carter Center not long after the news of the 92-year-old Bush’s passing in Houston “She touched the hearts of millions with her warmth, generosity, and keen wit. The matriarch of a family dedicated to serving, she urged volunteerism as a way for all citizens to participate in our nation’s progress. Through her own work to promote literacy as a value in every American home, countless families now have the knowledge and skills they need to thrive in all aspects of their lives. She will be missed.”

Jimmy Carter, 93, was elected president in 1976. Four years later, he lost his bid for reelection to Ronald Reagan, whose vice president was George H.W. Bush, who was married to Barbara for 73 years. The Carters will mark their 72nd wedding anniversary on July 7.
