[Non-Sequitur]

Lincoln's coffin was opened and the body identified one last time before it was laid to rest on September 26, 1901.

And when it was laid to rest in 1901 it was under tons of reinforced concrete to make sure no future grave robberies were attempted.

"And when it was laid to rest in 1901 it was under tons of reinforced concrete to make sure no future grave robberies were attempted."

Yes, from what I've read, it was Robert Todd Lincoln who requested that. He's buried in Arlington National Cemetery, and until recently, I didn't realize his only son, Lincoln's only grandson, is buried there with him. He died quite young and with him died the Lincoln name from that line.
