When German biologist Ernst Haeckel publishedArt Forms in Nature, it encapsulated his response to Charles DarwinsOn the Origin of Species. But Haeckel also clearly saw his illustrations as more than just scientific documentation. His elaborate forms have been called a precursor to art nouveau, and his influence even stretched to architecture. Haeckels work is preserved in the Library of Congress, the worlds largest library, holding more than 162 million items.
