Final answer:
Thurgood Marshall was the NAACP attorney in charge of the Brown v. Board of Education case, leading to a historic Supreme Court ruling against school segregation.
Step-by-step explanation:
The NAACP attorney in charge of the landmark case Brown v. Board of Education was Thurgood Marshall. Marshall successfully argued before the U.S. Supreme Court and later became its first African American justice.
In the years leading up to Brown v. Board of Education, the NAACP led a legal fight against segregationist policies. James Nabrit was also one of the lead attorneys for the NAACP in this case. This was part of a broader strategy by the NAACP, under the leadership of lawyers like Charles H. Houston and later Thurgood Marshall, to challenge the Separate but Equal doctrine established by Plessy v. Ferguson.
The collective efforts played a crucial role in the battle for civil rights and the eventual ruling in 1954 that declared school segregation unconstitutional.
