I was looking at Amazon's List of Bestselling Authors and noticed the claim that Dr Seuss (which rhymes with "voice", by the way) won three Academy Awards.
However, a look at his award page on IMDb doesn't list any.
Turns out that two films he co-wrote won Oscars (one for animated short and one for feature-length documentary) but, of course, those Oscars go to the producer(s).
Haven't found the third yet.
There may be broken links to media on this page. I'm still in the process of migrating them over.
