From its organization in 1891, the Daughters of the Republic of Texas became leaders in this work. They assisted in establishing the boundaries of the battlefield, placing granite boulders on significant sites, and induced the State Legislature to appropriate money for buying and improving the land.
In 1936 the State and Nation began the erection of the memorial shaft to honor all Texas heroes. In 1939 San Jacinto Chapter Daughters of the Republic of Texas, acting as trustees for the veterans, erected the sundial, thus completing the work started eighty-six years before.
