Langsdorff (aka Grigori von Langsdorff) was a Prussian naturalist that explored the Aleutian chain in the first years of the 19th century. Part of one of the first attempts at circumnavigating the world, Langsdorff worked as the onboard naturalist of Russian expeditions in Alaska.
Historical records suggest that Langsdorff was the first to bring the common yellow monkey flower (Mimulus guttatus DC) into Europe.
