Serenity Prayer

...did you know that the AA Serenity Prayer was origninally penned by Niebuhr? I am reading through some of Schlesinger's and Niebuhr's papers for my introduction and found this out---maybe this was conventional wisdom but it was one of those "isn't history the coolest damn thing ever."

I did not know that, and it looks like Jeff is right. History is cool.
