TOPEKA, Kan.  — As a girl in Kansas, Linda Brown’s father tried to enroll 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 U.S. Supreme Court followed, striking down racial segregation in schools and cementing Linda Brown’s place in history as a central figure in the landmark case.

Funeral officials in Topeka said Brown died Sunday at age 75. A cause of death was not released. Arrangements were pending at Peaceful Rest Funeral Chapel.

Her sister, Cheryl Brown Henderson, founding president of The Brown Foundation, confirmed the death to The Topeka Capital-Journal. She declined comment from the family.

Sherrilyn Ifill, president and director-counsel at NAACP Legal Defense and Educational Fund Inc., said in a statement that Linda Brown is 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.
