It was a bit of a "novelty" font for typewriters. Almost like the Comic Sans of its day. It wasn't meant to be used as italics, it was for typing a fun invitation or more "personal" letter or something like that.
I can't find any information on it specifically though, whether it was the first. It wouldn't surprise me if it were, however.
