I grew up in Italy, left in 2008 at age ~30, and been living in the US since 2012. I've only barely heard about "Dr. Seuss", and had no idea who he was. I've now read the article and it seems that he's been an important figure for many Americans, and possibly for many people around the world (not much in Italy). In the article a multi-faceted figure emerges, as if you wouldn't be able to guess much of it just by read…
I vividly remember the weird artwork of "I Had Trouble in Getting to Solla Sollew" as a kid.
Also prominent in my memory were: The Cat in the Hat, Green Eggs and Ham and Fox in Socks.
