Humboldt Monument in Chicago

Just to add to previous entries: I've discured yet another Humboldt monument. It's located in Chicago. Here is two references; later, I'll add them to the map and the blog entry below:

• http://www.chicagonow.com/blogs/unknown-chicago/2009/11/statue-4-answers.html
• http://www.explorechicago.org/city/en/things_see_do/attractions/park_district/alexander_von_humboldt.html

Naturally, I'm interested in getting similar references to other Alexander von Humboldt statues / monuments.
