While Charles Dodgson, aka Lewis Carroll, did, in fact, photograph nude prepubescent children there is no evidence to suggest that he ever sexually abused children. While I grant that to our modern, post-Freudian eyes he looks like a giant pedophile, the Victorians did not believe there was a sexual dimension to children and didn’t find his hobby perverted. Indeed, IIRC parents were quite proud when Dodgson wanted to photograph their children.

What makes you so sure? Pornography has existed in one form or another ever since our ancestors first began painting on cave walls and baking statues of clay. The word itself is derived from two Greek words, and the name dates to the Victorian era, during which Dickens was one of England’s most prolific writers.

Dickens himself may not have been a pornographer, but both the word and concept existed during his lifetime.
