Final answer:
Thurgood Marshall is the Civil Rights leader identified with the Supreme Court's decision in Brown v. Board of Education, which ruled that "separate but equal" has no place in public education.
Step-by-step explanation:
The Civil Rights leader identified with the decision to rule that "separate but equal" has no place in public education and that separate educational facilities are inherently unequal is Thurgood Marshall. This decision stems from the landmark Supreme Court case Brown v. Board of Education of 1954. As the lead attorney for the NAACP, Marshall played a crucial role in arguing this case, which successfully overturned the Plessy v. Ferguson decision and the segregation complained of by African American plaintiffs.
