This guy is Auguste Comte. You may or may not have heard of him, but he influenced Marx, the Italian and French school of criminology, the second republic of Brazil and many others. Before there was Marx, Comte already came up with the idea of historical determinism. He is no one less than the inventor of positivism, along with his mentor, Henri de Saint Simon. Both are children of the napoleonic regime, which was itself a direct descendant of the French Revolution.
I named Comte because he illustrates extremely well what I have in mind: To trace the ideas of all the tyrants of our age back to their roots, and create a kind of mindmap or genealogy for them. My question is who else would be up for a project like that
