Final answer:
The text does not provide information about a person named Foster or the specific number of schools they opened before 1962, focusing instead on the history of educational provision for African Americans and efforts surrounding school segregation and desegregation in the United States.
Step-by-step explanation:
The information provided does not specifically mention any individual named Foster or the exact number of schools opened by this person before 1962. The text focuses on the broader history of school segregation, desegregation efforts, and the educational initiatives for African Americans, including the Freedmen's schools and the Rosenwald schools. The data refers to school building programs and how certain states, politicians, and groups responded to the Brown v. Board of Education decision, which called for desegregation.
For instance, the Rosenwald School Building Program, which lasted from 1917 to 1932, created 5,357 public schools, shops, and teachers' homes to improve the educational opportunities for Black students in the Southern states. However, there was continued resistance to desegregation after the 1954 decision, with political measures such as 'The Southern Manifesto' and actions by individuals like Governor Orval Faubus and Governor George Wallace, who both actively worked to prevent the integration of schools.
Without additional context or clarification regarding who 'Foster' refers to, it is not possible to determine how many more schools were opened by this individual before 1962. The provided excerpts focus on the general environment and circumstances surrounding the education of Black students and the Civil Rights Movement rather than the efforts of a single individual named Foster.
