Horner Middle School (now Hosanna House) - Northeast African American Historic Places Map (sitios de interés)

Black and white students attended this school during the 1930s through the 1950s, making it one of the few institutions in Wilkinsburg where racial intermingling occurred before mandatory desegregation in the 1960s. Allegheny County Court of Common Pleas Judge Livingstone Johnson was a student here. His father, Oliver Livingstone M. Johnson, was the first black Assistant District Attorney in Allegheny County, who served from 1942 to 1948. The Johnson family grew up at 1131 Ross Avenue in Wilkinsburg, a house that still stands but is abandoned.
