I thought the founder of modern body building was Eugen Sandow?

Sandow is on the Olympia trophy. I doubt you could call the turn of the century modern bodybuilding.
Side note: There is a good website if you like to check out the old time bodybuilding (physical culture) books.

Later Charles shows who is the real man!
Can't be forgetting about Charles Atlas!
