We've added the following to our well-known ship manifest page:
1873 Thomas Edison
1896 Franklin Roosevelt
1911 Thomas Edison
1912 Henry Ford
1913 Harry Houdini
1910 Theodore Roosevelt

All can be linked to from

More are in the works. Suggestions can be sent to me at mjnrootdig@gmail.com
Apparently Harry didn't always hide from the guy creating the manifest.
