My reading of AlwaysUnite’s post is that s/he didn’t create it but found it on the web. I agree about its awesomeness, though. According to a book about Venn diagrams called “Cogwheels of the Mind”, a diagram almost identical to this one was constructed by Branko Grünbaum in 1975. The Grünbaum construction is more symmetrical and uses five congruent ellipses, which is cute but produces some rather small and thin regions. Here’s one version of it.
If you like this diagram, you might also like the one found near the top of this page, for seven sets.
