Inspired in part by this question, I am curious how the Holocaust came to be represented in American school history curricula. Obviously every American history teacher has a different curriculum, but most people I've talked to across multiple towns and states covered the Holocaust to varying degrees of depth (my school spent a full quarter on the topic). But a century ago no one learned about the Holocaust, for obvious reasons. Now many if not most schools spend a good amount of time on it. This means at some point school curricula had to start to change, and as anyone who has ever worked on curricula will tell you, that can be a bit of a mess.

Who pushed to add the Holocaust to history curricula? Who pushed back? What arguments were made for/against these changes? Was there a "Sputnik Moment"-style that led to dramatic changes in education, or was the transition more gradual?

Additionally, how has Holocaust education evolved through the years? How have the debates that exist within the academy (i.e. functionalism vs. intentionalism; I don't mean those who dispute the obvious facts) trickled down into middle/high school classrooms?
