Alexander von Humboldt Statue in Philadelphia

Here is a description:

The statue of Alexander von Humboldt by Frederick Drake, erected by German-American citizens now stands along West River Drive along the Schuylkill River south of the Belmont Pumping Station, near a more famous statue of Saint George and the Dragon which is not from the Centennial.

Unfortunately, I haven't been able to find a good photo of the statue yet. However, this is another reference.
