Dolores B. Linton, a black teacher, is known for her contributions to the black community in San Antonio. Dolores was born on February 21, 1910, in Seguin, Texas. Dolores began teaching in Pleasanton, Texas until the needs of the poor, isolated black community of West San Antonio Heights came to her attention during a visit in 1931. On her visit, she learned the closest school for black children was miles away with no transportation.

After gaining permission to use Paradise Cove, a former dance hall for classes, she organized the parents' petition to request public funds for the school. Dolores took on the responsiblity of teaching all six grades herself. Three years later the county built a one room schoolhouse, without water, for her 30 students.

Dolores married Walter Linton in 1937. During World War II, she took a break from teaching to work briefly for the USO before returning to the West San Antonio Heights school. In 1946, a barracks building was moved onto the former site of the dance hall. This provided a two room school facility. The building still had no water, electricity, or indoor plumbing. In 1952, due to Dolores' persistence the school board finally constructed a modern four room school.

Dolores continued to teach multiple grades until a court order forced racial distribution of students in 1966. NISD had to transfer Dolores and her students. Dolores taught at Thunderbird Elementary School until retiring in 1971. A new school was named for her in 1980, in honor of her commitment to equal educational opportunities. She died on November 19, 1980 at the age of 70 in San Antonio. She was honored posthumously in 1981 with the Human Relations Award from the Texas State Teachers Association.
