Steller's classic work, published in Latin in 1751 and in German in 1753, contains the only scientific description from life of the Steller's sea cow (Hydrodamalis gigas), as well as the first scientific descriptions of the fur seal or "sea bear" (Callorhinus ursinus), Steller's sea lion (Eumetopias jubatus), and the sea otter (Enhydra lutris). Steller's sea cow was a sirenian, or manatee, inhabiting the North Pacific Ocean and Bering Sea. It was first discovered by Europeans in 1741 and rendered extinct by 1768. It was a 30-foot long, plant-eating aquatic mammal, weighing up to 12 tons, that lived in large herds on the coasts of Alaska and Kamchatka. Steller made his observations as part of Vitus Bering's second voyage, during which the crew was shipwrecked for 9 months on Bering Island, from November 1741 to August 1742.

By the 1980s the Soviet scientific establishment had become the largest in the world, but very little of its history was known in the West. What has been needed for many years in order to fill that gap in our knowledge is a history of Russian and Soviet science written for the educated person who would like to read one book on the subject. This book has been written for that reader. The history of Russian and Soviet science is a story of remarkable achievements and frustrating failures. That history is presented here in a comprehensive form, and explained in terms of its social and political context. Major sections include the tsarist period, the impact of the Russian Revolution, the relationship between science and Soviet society, and the strengths and weaknesses of individual scientific disciplines. The book also discusses the changes brought to science in Russia and other republics by the collapse of communism in the late 1980s and early 1990s.
