A funeral for retired Judge Calvin Mapp, the first black judge in Miami-Dade County Court, will be 11 a.m. Saturday at the Historic Mount Zion Missionary Baptist Church.

Mapp, who died Nov. 27 at 88, also was one of Miami’s first black police officers in the city’s Central Negro District during segregation. He would later serve as a prosecutor and help launch Matthews Braynon & Mapp, Miami’s first black firm, before being appointed a county court judge in 1973.
