The great-great-grand papa flerf of the modern flat earth movement is undoubtedly Samuel Rowbotham.

Flerfs claim he was a doctor. No such records exist. His history has been told in several different places, I will include links to these. However, there are a few notable things to include.

He killed his own daughter with strychnine. This is not mentioned by the flat earthers that idolize him.
