It's E.E. Cummings
Just catching up with the Chicago Tribune op-ed piece on the trend to write in all-lowercase letters. The article included a sentence, “caplessness worked for e.e. cummings, right?” Once and for all, Edward Estlin Cummings indulged in many typographical effects in his poetry, but he capitalized his name conventionally.
Here is an article by Norman Friedman that includes a reproduction of his signature and a comment from Cummings’ widow that insisting on lowercasing his name was “stupid & childish.”
I think that it’s an annoying affectation* with people like k.d. Lang and bell hooks (K.D. Lang! Bell Hooks” There! Sue me!), but ascribing the practice to Cummings is doubly annoying.
* I’m irresistibly reminded of Sarah Jessica Parker’s character, SanDeE* in L.A. Story.
