Teaching: History of American Atheism

I'm in the process of preparing a class on the history of American Atheism, which, as far as I can tell, is more or less uncharted territory. Existing studies and curricula seem to either be philosophical examinations of atheism (e.g.), or much too narrow for my interests (e.g.), or really more hagiographical canonization efforts than I am comfortable with (e.g.). Not to mention the very common whig histories of atheism.

Given the new(ish?) direction of the class I'm designing, it seems some readers might be interested in the shape of the class as it develops. Also, as there's no standard text outlining major figures or movements in American Atheism, I would appreciate readers' help in identifying critical people and/or texts to teach.

Below, I've listed those I have in mind who are important in this history and who I think can be taught fairly well to first and second year students with an interest in religious history and American cultural studies. I've construed "atheist" fairly broadly, to include some agnostics and skeptics (especially if they expand the possibility of disbelief); as well as some who's opposition to specific faith traditions is clear while their own position is more ambiguous; those of the political right as well as the more well-represented left; some who are hostile towards religion and some who attempt to make use of religious rhetoric. I've also tried to work in a fair representation of non-whites, women, and, as far as possible, some from backgrounds other than Protestant.

Are there any significant figures or movements I'm missing?

Anyone who would likely teach particularly well that I haven't thought of?

Course description:

From Cotton Mather’s denunciations to Daniel Dennett’s proposal atheists rebrand themselves as “brights,” atheists have been a much-discussed but little understood feature of the religious landscape of America. This class will take a historical approach to the subject, analytically examining the many varieties of atheism in America. Students will learn about atheisms, plural, in the past and present, and will study their cultural contexts, as well as arguments for and against the existence of God, and vying conceptions of meaning and morality. Students will also be introduced to the methodological issues in the study of the history of religion, gaining a working understanding of the approaches entailed by cultural history.
