I'd note what was a skyscraper back then is not today. Plus there are a lot of structures that are partially habitable like the Eiffel tower or Great pyramids, some cathedrals in Europe etc. As far as fully habitable buildings go, even if Chicago got the title back then, it's not considered a skyscraper anymore at all.

The CTBUH is a joke anyways. To them the Bank of America Tower in NYC is taller than the John Hancock Center in Chicago.
