Miss Anne was known for her knowledge of cattle, horses and fine art. She established the $200 million Burnett foundation in 1978 to support projects ranging from horse ranching to museums. She divided much of her time between her home near the Shady Oaks Country Club in Fort Worth and the Triangle Ranch that her father established near Iowa Park, Texas. Along with her second husband, James Goodwin Hall, she assisted in the formation of the American Quarter Horse Association (AQHA). She was a founder of the American Quarter Horse Hall of Fame. Miss Anne had only one child - also named Anne but often called “Little Anne” - from her marriage to James Goodwin Hall. In 1969, Miss Anne married Charles Tandy, founder of the Tandy Corporation. Prior to his death in 1922, Miss Anne's grandfather, Captain Samuel “Burk” Burnett, willed the bulk of his estate to Miss Anne in a trusteeship for her yet unborn child. At the time of Miss Anne’s death on Jan. 1, 1980, her daughter Little Anne - Anne W. Marion - inherited her great-grandfather Captain Burnett's ranch holdings through directives stated in his will. She then sold the Triangle Ranch her grandfather Tom Burnett had developed and donated the Burnett home in Iowa Park to the city for use as a library.
