Established in 1976, it is named in the honor of John A. Brashear, an astronomer and inventor. It was created to help with segregation issues in the Pittsburgh Public Schools. The Pittsburgh Board of Education closed Fifth Avenue High School, Gladstone High School in Hazelwood and South Hills High School and merged the students in the building with 5000 or more students attending. The school opened with protesters from Brookline and Beechview communities, as well as the Hill and Hazelwood, the school had mass media coverage, and School Security and local Police were on hand the first week of school in 1976. The school colors are black and gold, and the original school mascot were Bullets, depicted by two large bullets with mean faces and fists clenched. They were replaced in the mid-1990s with a new mascot the Bull in response to parental complaints that the Bullets mascot could incite violence in students.
