John Mercer Langston School: This building is an exceptional example of an African American school built during DC’s segregated school system era.
Text
John Mercer Langston School was built in 1902 to handle the overflow of students from neighboring John Fox Slater School. Named for John Mercer Langston (1829-1897), the first African American congressman from Virginia, who also had a distinguished career in DC, the school was one of several schools for African American children along the North Capitol Street corridor.
In the late 1910s, it merged with Slater School to become Slater-Langston and, in 1951, became an independent school once again. The red brick two-story Italianate style building was designed by influential architect Appleton P. Clark. The eight classroom school has two towers on the front elevation marking the girls’ and boys’ entrances.
