Wading In: Desegregation on the Mississippi Gulf Coast frames the fight for beach and school desegregation within the history of Black life in Biloxi, beginning with the arrival of slave ships on the Gulf Coast islands in 1721. Detailing the buildup of Back-of-Town businesses, lynchings in the early 1900s, and national and state legislation repressing Black progress, author Amy Lemco contextualizes the regional atmosphere Dr. Gilbert Mason--a resilient civic leader, humanitarian, and lover of the water--and his family encountered in 1955. Using extensive archival records and interviews with survivors, the book chronicles how Dr. Mason inspired and helped organize local Black activists to peacefully protest the apartheid of Biloxi's beaches. Dr. Mason operated under the surveillance of the State Sovereignty Commission, assaults by private citizens, and the terrors of a decade riddled with the assassinations of civil rights workers. Grassroots efforts he led and inspired in Biloxi joined with the national movement to weaken the hold of white supremacy in the state. With unwavering perseverance and bravery, Dr. Mason and fellow activists achieved the desegregation of Mississippi's beaches and made Harrison County schools the first primary school district in the state to integrate. Wading In firmly establishes Dr. Mason as a national civil rights role model and presents the story of Mississippi's struggle to a new generation of readers.
