Quoting AEnigma III:

..........I am still trying to find a mystery rich man!
(preferably very old, with a low libido, a heart condition and no children to inherit his wealth )

Quoting AlphaF:

He was treated for cirrhosis, but he did not have that disease (wrong diagnosis). The medicine they used to treat him was mercury based (wrong and fatal treatment); questioned by many at the time, totally banned now.

His liver totally disappeared after post mortem. In a situation where everything was photographed and recorded, there seems to be no records of what happened to the remains of his liver.
