You should of heard basic background information about Krav Maga and it's founder at your first classes.. It is part of the lesson plan, and an important part at that. Every student should know the history of the MA form they are taking. I give my student's a brief history, if they need more I will talk to them outside of class or give them the resources to research it on their own. To give the complete history would take the entire class time if not longer. It is definaltly worth learning.
