TOPEKA, Kan. (AP) — Crews have put out a small fire at a former all-white school that played a role in the historic Brown v. Board of Education desegregation case.

The Topeka Capital-Journal reports that the fire was reported around 12:45 p.m. Wednesday at the old Sumner Elementary School building. The cause wasn’t immediately known.

In 1950, Linda Brown’s father, Oliver Brown, tried unsuccessfully to enroll his daughter at Sumner School. Several other black Topeka parents also tried to enroll their children in all-white schools.

They sued, and that case was combined with similar cases from Virginia, South Carolina, Delaware and Washington, D.C. The case led to the Supreme Court’s 1954 ruling that overturned segregated education.

The former Sumner School has remained empty since it was auctioned in 2009 to a religious group.
