As tributes pour in across the world, Barbara Bush is remembered as a matriarchal figure of a political dynasty that included two presidents - her husband George HW Bush and son George W Bush. According to BBC reports, Mrs. Bush, who was first lady from 1989 to 1993, had been in failing health for some time and had declined further medical treatment.
Her husband, at 93, is the longest-lived US president. Their son, George, was elected in 2000 and served two terms as the nation's 43rd president. In his eulogy George Bush Junior said her mother had passion for the welfare of others and championed literacy programmes.
He is quoted in a statement: "My dear mother has passed on at age 92. Laura, Barbara, Jenna, and I are sad, but our souls are settled because we know hers was. Barbara Bush was a fabulous First Lady and a woman unlike any other who brought levity, love, and literacy to millions."
Mr. Bush further said his mother had "kept us on our toes and kept us laughing until the end", adding: "I'm a lucky man that Barbara Bush was my mother. Our family will miss her dearly, and we thank you all for your prayers and good wishes."
Mrs. Bush was also the mother of Jeb Bush, who served as governor of Florida from 1999 to 2007 and unsuccessfully ran for the White House in 2016.
As first lady, Mrs. Bush went beyond the traditional role of a political spouse, founding the Barbara Bush Foundation for Family Literacy to help parents and children from disadvantaged communities to read and write.
In a statement from the White House, President Donald Trump said Mrs Bush would be long remembered for her devotion to country and family, "both of which she served unfailingly well".
Former first couple for the US, Barack and Michelle Obama, described her as "the rock of a family dedicated to public service" and as "an example of the humility and decency that reflects the very best of the American spirit."
