We're pleased to welcome the Tulsa-based attorney, historian, and author Hannibal B. Johnson back to StudioTulsa. An active and well-respected expert on matters of diversity, inclusion, and social justice, Johnson is also the education chair for the 1921 Tulsa Race Massacre Commission. He joins us to discuss his newest book, "Black Wall Street 100: An American City Grapples With Its Historical Racial Trauma." As was noted of this volume by Dr. Scott Ellsworth of the University of Michigan's Department of Afroamerican and African Studies: "The remarkable story of Tulsa's African American community and the racial cataclysm of 1921 bear important lessons for us all. Few know these better than Hannibal B. Johnson. [This book] is essential reading."
