Sannikov Land
Eduard Gustav Freiherr von Toll (; 1902), better known in Russia as Eduard Vasilyevich Toll and often referred to as Baron von Toll, was a Baltic German geologist and Arctic explorer. He is most notable for leading the Russian polar expedition of 1900–1902 in search of the legendary Sannikov Land, a phantom island purported to lie off Russia's Arctic coast. During the expedition, Toll and a small party of explorers disappeared from Bennett Island, and their fate remains unknown to this day.
