Roosevelt High School is a public high school in St. Louis, Missouri that is part of the St. Louis Public Schools. Roosevelt opened in 1925 after two years of construction and the evacuation of a cemetery for the building site. From the 1930s through the 1970s, Roosevelt served a predominantly white, ethnically German population, and among its graduates was Clyde Cowan, the co-discoverer of the neutrino particle. As a result of intradistrict busing in the 1980s and 1990s, Roosevelt served increasing numbers of black students, and it continues to be among the most integrated comprehensive schools in the district.
