Director 'One Hit Wonders'....

[Trevor]

yeah, but I'm just talking about guys who literally directed one movie 

Oh, got it.

James William Guercio who directed Electra Glide In Blue.

[RCMerchant]

The guy who made DEMENTIA/DAUGHTER OF HORROR.

Almost nothing is known of his life. (He has another IMDB credit but it appears to be just a remix of DAUGHTER OF HORROR by someone else decades later).

It's rumored that the film was actually directed by producer Bruno DeSota, who's best known as an actor (remember the fat guy in ATTACK OF THE GIANT LEECHES?).

I think even DeSota himself only claimed to have co-directed it.
