Urgently need to fin who came up with the 7 principles of magic theory

Feb 19, 2017
Hey guys
I'm writing an academic paper for a university assignment and in it I talk about the 7 principles of magic (palm, steal, ditch ect), and I need to reference who came up with it,
but I can't find who first mentioned that theory. The only thing google says is that Penn and Teller talk about it in their cigarette act.
Can someone please help?
