"From Slavery to Freedom" remains a work in progress that awaits final touches and tweaks, according to curator Samuel W. Black. He is director of African-American programs at the Heinz History Center.
Additional material on Pittsburgh's role in the Underground Railroad and the 20th century's civil rights struggles will be put in place in the coming weeks. The deadline for completing that work is Jan. 21, the national holiday that marks the birthday of Martin Luther King.
An already installed interactive map will be augmented by displays and more information on the Underground Railroad that helped slaves head north to freedom.
"We'll show who was involved, the different kinds of activism and identify the location of safe houses," Mr. Black said. "There will be stories about some local folks that most people will never have heard of."
Pittsburgh's role in the 19th century abolition movement through groups like the Western Pennsylvania Anti-slavery Society also will be highlighted.
New displays will be installed that link stories about abolitionists to the people and institutions that fought for civil rights. They include newspapers like the Pittsburgh Courier.
That section will also look at the impact of the Great Migration from the south. That movement of people more than quadrupled Pittsburgh's black population in the first 40 years of the 20th century, Mr. Black said.
