***I don’t doubt he was alive when Lincoln was assassinated. Anyone in their nineties would have been in 1956.***
I remember when LIFE magazine did an article on LINCOLN.
They had an interview with the last living person who looked on the face of Lincoln in his coffin. This article was in either the late 1960s or early 1970s.
He was just a child at the time, and it was just before they opened the casket for the last time in Springfield Ill, and closed it back up, then poured cement around it to protect it from grave robbers, as the body had almost been stolen once before.
I read a report of what that witness had to say on the net about ten years ago, complete with photos of the scene (but not of Lincoln's body).
The Man Who Last Saw Abraham Lincoln
“with the death of Fleetwood Lindley on February 1, 1963 the world lost the last person to look upon Abraham Lincoln’s face.”
