Laura Bush was a librarian

Laura Bush was a librarian before becoming the First Lady of the United States. She earned a Master's in Library Science from the University of Texas at Austin in 1973 and worked as a librarian in public and academic libraries. In the 1980s, she was the librarian at the Sidwell Friends School in Washington, D.C., where her husband, George W. Bush, served on the board of trustees. Laura Bush has advocated for literacy and education throughout her career, and she used her position as First Lady to promote reading and library programs. In 2001, she established the National Book Festival, an annual event that celebrates books and reading and brings together authors, illustrators, and readers from across the country.
