Who was the chief lawyer for the NAACP in the brown case?

The chief lawyer for the NAACP in the Brown v. Board of Education case was Thurgood Marshall. He played a pivotal role in arguing that racial segregation in public schools was unconstitutional, ultimately leading to the landmark Supreme Court decision in 1954 that declared segregation in public education illegal. Marshall's efforts laid the foundation for the Civil Rights Movement and he later became the first African American Supreme Court Justice.
