The Manassas Industrial School for Colored Youth, commemorated as the Jennie Dean Memorial Site, was a former school for African-American children in Manassas, Virginia. The current site name honors the school's founder, Jennie Dean, a charismatic ex-slave who believed in the value of vocational education for African-American youth of both sexes. Dean and other African Americans established the school as a private residential institution in 1893. In 1938, after the Virginia Supreme Court finally interpreted the 1902 state constitution's free public education requirement as mandating public schools for African American children as well as white children, a regional public school system took over operations and ran the school until 1959. Thus, for approximately two decades between 1938 until 1958, the Manassas Industrial School formally became the only school for secondary education of African American students in five northern Virginia counties. After World War II, northern Virginia's population increased and the NAACP followed victories improving salaries for black teachers and allowing black children to receive bus rides to segregated schools by litigating directly against segregated schools. This led to several important court decisions against segregation in the 1950s and 1960s, including Brown v. Board of Education and a companion case from Virginia. Opponents of integration initially implemented a massive resistance strategy, which initially closed schools integrating even pursuant to court order, but eventually led to integrated schools. The Manassas Industrial School closed in 1959, after the Virginia Supreme Court and a three-judge panel of federal judges both separately ruled on January 19, 1959 against the core Virginia Massive Resistance legislation. The Manassas Industrial School buildings were demolished and a new elementary school with ball fields and park facilities constructed nearby. A series of historic markers was erected on the property and the site landscaped. In September, 2015, the school's class roster for 1927 was discovered. The Principal was William C. Taylor. Class colors were Red and Black. Class flower was a White Rose. Class roll was: William Henry Bailey, Garnetta Cornelia Battle, Ruth Estelle Clarke, Edward Albert Chambers, Naomi Agusta Dean, Edith Mae Gaskins, Harry Wilson Hall, Virginia Kelley Kenny, Paul Emanuel Rier, Adrian Francais Robinson, Mary Viola Roberts, Kathleen Lewisha Thomas, Rosa James Thomas, Tasco Delany Thomas, Hazel Belle Voorhees, William Henry Waddell, George Shermy woodson, Roberta Josephine Waters and Mary Synora Waller. Class motto was: Pick out you peak and climb. The site was added to the National Register of Historic Places in 1994.
