Did a specific person dream up the "Atheist Atom"?
American Atheists (the non profit, not the people in the US who have concluded that there is no supernatural deity) has a symbol that looks like the Rutherford atom schematic, with an A in the middle.
It is clearly an accepted symbol-it is the atheist symbol on graves in Arlington Cemetery. If you have been to the cemetery, you have seen it.
Did a specific person think that one up?
