A $20,000 acrylic case now protects Thomas Jefferson’s original headstone on the University of Missouri campus, a response to vandalism concerns amid an ongoing dispute about whether the university should honor the third president who also was a slave owner.

The Columbia Daily Tribune reports that the clear case was installed Saturday over the granite obelisk that was originally erected at Monticello in Virginia in 1833. It was replaced in 1883 and given to the University of Missouri.

A university spokesman says the case was installed because of vandalism to a Jefferson statue that is also on campus, and graffiti written on the sidewalk during the summer.

MU Chancellor Mun Choi this summer refused to remove the Jefferson statue, which prompted MU student Roman Leaphart to begin a petition drive, seeking removal of the monument to “a racist slave owner.”

There are two relics associated with the grave marker. The obelisk holds a replica of a marble plaque with the inscription Jefferson wrote for his grave: “Here was buried Thomas Jefferson; Author of the Declaration of American Independence; of the Statute of Virginia for religious freedom; Father of the University of Virginia.”

It’s unclear why the marker was given to the university, but the University of Missouri is the first state university established in the territory of the Louisiana Purchase, which was made when Jefferson was president, and it was established with the University of Virginia as a model, it was reported.
