In 1994 graffiti from the 1800s was discovered by workers renovating the Washington Monument. The graffiti has quite a different tone from the graffiti found today on the sides of buildings and subway cars. It reads: "Whoever is the human instrument under God in the conversion of one soul, erects a monument to his own memory more lofty and enduing (sic) than this," reads the inscription which can now be viewed by visitors to the monument. It is signed BFB. No one knows who that is, or who left the small drawings and 19th century dates on other walls.

The markings in the lobby of the monument were covered over when it was decorated at the turn of the century. They were found when workers removed marble wainscoting as part of a year-long $500,000 renovation which was just completed.
