Former First Lady Barbara Pierce Bush died Tuesday, April 17, 2018, at her Houston home. She was 92.

The matriarch of the Bush family was an outspoken public figure and spent countless hours volunteering. Her most ardent cause was literacy. While her husband, George H.W. Bush, was president, she founded the Barbara Bush Foundation for Family Literacy. After leaving the White House, she continued to advocate for literacy for children and adults, and authored several books.

Her long history as an advocate for education prompted TCTA to honor Bush as a Friend of Education in the Private Citizen Category in 1996. She was nominated by Baytown CTA for TCTA's highest honor because "she used the visibility of her status as a first lady and her personal popularity to educate the public about the lifelong rewards that accompany literacy."

Bush joined Abigail Adams as the only women to be both the wife and mother of U.S. presidents. Often known as America's grandmother, due to her prematurely white hair, Bush had six children, 17 grandchildren and seven great-grandchildren. 

Messages from leaders and admirers across the nation flooded social media, remembering Bush for her passionate work in literacy and volunteer work.
