This is a very bizarre story, but one that demonstrates the immense power of the media industry on public history. Spielberg's Lincoln has inspired Highgate Cemetery to remember Lincoln's chiropodist, Dr Isachar Zacherie. Hundreds would have walked past his grave, with no clue of who he was, but now the cemetery are putting him on the map. Literally. The graveyard guide is now being updated to include Dr Zacherie, who worked on Lincoln's feet in 1862 and treated Union soldiers.
