Georg Wilhelm Steller and the Great Nordic Expedition

Reconstruction of Steller’s Sea Cow

On March 10, 1709, German botanist, zoologist, physician and explorer Georg Wilhelm Steller was born. He joined the Russian explorer Vitus Bering on his second expedition to Kamchatka and Alaska, where he discovered numerous new species, as e.g. the Steller’s sea cow that was named after him.

Georg Wilhelm Stöller was born and grew up in Windsheim, Germany. Due to his father being a protestant church organist, Steller early decided to begin studying theology in Wittenberg, but after some time his interest in medicine and nature science grew so much that he decided to fully dedicate his student life to medicine, graduating at ‘Obercollegium medicum’ at Berlin in 1734.

Shortly after his graduation, Stöller moved to Saint Petersburg connecting with fellow scientists like Johann Ammann at the Academy of Sciences. This is also when, due to problems transcribing his name into cyrillic letters, his name was changed into Steller. When finding out about an open position at a recent Kamchatka Expedition he applied, was accepted and left Saint Petersburg in 1737. His journey was interrupted by an unplanned stop of a whole year in Irkutsk, where he documented 1152 plants in his ‘Flora Irkuntiensis manuscript. The first meet with Vitus Bering took place in 1740 not far from Ochotsk. Vitus Bering was a well known explorer and officer of the Russian Navy, with an amazing reputation due to his later explorations of the north-eastern coast of the Asian continent and the western coast of the North American continent. However, Steller and his fellow travelers continued their way to the southern island of Kamtschatka studying its nature and civilization. Vitus Bering back then prepared for his trip to America from Kamtschatka, inviting Steller to come along on his Boat called ‘Sankt Peter’, which he gratefully did.

The explorers’ ship reached Kayak island near Alaska’s dry land, where Steller was able to document (due to time issues) a rather small catalog of discovered plants. The crew then managed to arrive a piece of land, that is now called Bering Island, where the head of the exploration, Vitus Bering passed away. Since their ship had to be fixed in order to return home, Steller took his time to explore the island resulting in the discovery of the famous and now extinct sea cow, named after Steller. In 1744, Steller began his journey home, passing away in November 1746 in Tyumen.

Even though, Steller discovered several animals and plants now named after him, the sea cow depicts one of the most famous and most important due to its short lifetime on Earth and its extinction due to over hunting the averagely 8000kg marine mammal. Unfortunately, the sea cow was according to Steller a slow swimmer and could not escape the many hunters following the Bering’s route. It was hunted for both, for food and its skin in order to manufacture boats out of them.
