The preservation of the Alamo as a historic site is primarily credited to the "Daughters of the Republic of Texas" (DRT), and specifically two women: Adina De Zavala and Clara Driscoll. In the late 19th century, the Alamo was in a state of disrepair, with part of it being used as a grocery warehouse. Adina De Zavala formed a chapter of the DRT to advocate for its protection, but it was Clara Driscoll who provided the significant financial backing, using her family's wealth to purchase the long barracks to prevent them from being demolished or sold to a hotel developer. This act in 1905 earned Driscoll the title "Savior of the Alamo." For over a century, the DRT managed the site until the state of Texas took over primary management in 2011. While the 1836 battle gave the Alamo its legendary status, it was these dedicated conservationists who ensured the physical structure remained standing for future generations to visit. Without their intervention during a period of rapid urban development in San Antonio, the chapel and barracks might have been lost to commercial interests, leaving only a commemorative plaque where the historic mission once stood.
