Ape Lad sez, "2719 Hyperion, a great blog about Disney parks and imagineering, has been posting a series of photos of gravestones from the Haunted Mansion grounds with an explanation of who each is named after."

One of Disney's legendary "Nine Old Men"of animation, Marc Davis also stands as one of the most influential and creative forces in the history of theme park design. His clever and highly detailed concepts were the basis for the audio-animatronic vignettes of both Pirates of the Caribbean and the Haunted Mansion, and his unrealized designs for Walt Disney World's Western River Expedition are among the great lost treasures of Disney Imagineering. He also contributed to other celebrated attractions including the Enchanted Tiki Room, the Jungle Cruise and It's a Small World.
