1. Mrs. Henderson's Legacy Marker
As you look up the hill, you can see Peter C. L’Enfant’s 1791 plan for Washington ended up here in front of you at Boundary Avenue, now Florida Avenue. Back then, when people walked or rode in horse-drawn vehicles, it was hard to climb this steep ridge. Once electric streetcars appeared in the 1880s, climbing hills was easier, so city dwellers began moving up this hill.
Beginning in 1887, Mary Foote Henderson, wife of Missouri Senator John B. Henderson, created a new community here for the wealthy and powerful. She purchased much of this area and built herself a castle-like mansion on this side of 16th Street. After she failed to persuade the U.S. Government to move the White House here, she did persuade it to set aside land for Meridian Hill Park (also known as Malcolm X Park). She hired noted architects to design a series of elaborate mansions. The French, Spanish, Mexican, Cuban and Polish embassies moved in, and a number of embassies remain today.
After Mrs. Henderson’s death in 1931, her castle became apartments and later a noisy after-hours club. A sleepless neighbor, Washington Post publisher Eugene Meyer, bought the castle and eventually razed it, but left a momento: the brownstone walls of Beekman Place, ahead on the left.
