A WOMAN who became a central figure in the fight against racial segregation in US schools has died at the age of 75.

Linda Brown died on Sunday in Topeka, Kansas, her sister Cheryl Brown Henderson, founding president of The Brown Foundation, confirmed.

As a girl in Kansas in the 1950s, Brown’s father tried to enrol her in an all-white school in Topeka. He and several black families were turned away, sparking the Brown v Board of Education case that challenged segregation in public schools.

A 1954 decision by the US Supreme Court followed, striking down racial segregation in schools and cementing Brown’s place in history as a key figure in the landmark case.

Sherrilyn Ifill, president and director-counsel at NAACP Legal Defence and Educational Fund, said in a statement that Brown was one of a band of heroic young people who, along with her family, courageously fought to end the ultimate symbol of white supremacy – racial segregation in public schools.

“She stands as an example of how ordinary schoolchildren took centre stage in transforming this country. It was not easy for her or her family, but her sacrifice broke barriers and changed the meaning of equality in this country,” Ifill said.

The NAACP’s legal arm brought the lawsuit to challenge segregation in public schools before the Supreme Court and Brown’s father, Oliver Brown, became lead plaintiff.

The lawsuit was joined with cases from Delaware, South Carolina, Virginia and the District of Columbia.

On May 17, 1954, the Supreme Court ruled unanimously that separating black and white children was unconstitutional.

“In the field of public education, the doctrine of ‘separate but equal’ has no place,” Chief Justice Earl Warren wrote. “Separate educational facilities are inherently unequal.”

Linda Brown and her sister founded the Brown Foundation for Educational Equity, Excellence and Research in 1988.

A cause of death for Brown was not released. Arrangements were pending at Peaceful Rest Funeral Chapel.
