Located from 1912 at 701 Frederick Street, across from Kezar Stadium, the school was in operation from 1884 until 1973. History. The school opened in 1884 as the Commercial School, on Powell Street between Clay and Sacramento. It subsequently moved to Bush and Stockton Streets. Academic subjects were added to the curriculum in 1890 and art and shop in 1895, when it was renamed San Francisco Polytechnic High School. The building was destroyed in the 1906 earthquake, and replaced in 1911  by a classical revival building on Frederick Street, which opened in 1915; a "manual and shop training" building facing Carl Street opened in 1912. Later additions included a boys' and a girls' gymnasium in art deco style, at opposite ends of the school. During this period the school had 2,000 students, more than any other in the city. In the 1960s an influx of black families led to an option system under which many white parents elected to send their children instead to Lowell High School, San Francisco Polytechnic's traditional rival; by the late 1960s San Francisco Polytechnic was  more than 50% African American and Filipino. The first black principal, Nathaniel Brooks, was appointed in spring 1968 and the numbers of black teachers and Black studies courses were increased after student protests about a letter to the Superintendent of Education from teachers complaining about the students. However, in 1972 the decision was made to close the school because of a continuing decline in enrollment and because all the buildings, except the girls' gym, were found not to meet the requirements of the Field Act for seismic soundness. In 1973 the school closed and students were transferred to the new  McAteer High School. The school was the temporary home of Mission High School from 1973 to 1977. Squatters occupied the buildings in the 1980s; in 1989 all except the two gyms were demolished and replaced by the Parkview Commons condominium development. The cornerstone was stolen during demolition. the boys' gym houses the San Francisco Circus Center and the girls', AcroSports.
