Early life
Vladimir Ivanovich Vernadsky was born on March 12, 1863 (February 28, Old Style), in St. Petersburg, Russia. He was the son of a professor.
Education and career
Vernadsky graduated from St. Petersburg University in 1885 and became curator of the university's mineralogical collection in 1886. In 1890, he became a lecturer on mineralogy and crystallography at Moscow University, where he earned his Ph.D. in 1897. He served as a professor at Moscow University from 1898 to 1911.
After the Russian Revolution, he was active in scientific and organizational activities; he founded and directed (from 1927) the biogeochemical laboratory of the Academy of Sciences at Leningrad (St. Petersburg).[1]
Notable/unique
Vernadsky is considered to be one of the founders of geochemistry and biogeochemistry. His initial work was in mineralogy, where he carried out highly detailed studies on aluminosilicates and was the first to correctly describe their chemistry and their structure, which forms the basis of many other minerals.
He was a pioneer in geochemistry, the measurement and study of the distribution and migration of the chemical elements and isotopes in the Earth's crust. He gathered detailed data on the layers of the crust, described the migration of atoms in such layers, tried to explain the occurrence of chemical elements in those layers, and studied the formation of chemical compounds under the influence of geologic processes.
Vernadsky was one of the first scientists to recognize the tremendous potential of radioactivity as a source of thermal energy, and he was also one of the first to postulate the long-term heat buildup from radioactivity as a driving force behind many geochemical processes.
His later years were taken up with the study of the contributions that life processes make to the atmosphere, and he correctly attributed to living things the creation of the oxygen, nitrogen, and carbon dioxide present in the atmosphere. He also studied the effects living things have on the chemistry of the Earth's crust.
Vernadsky is regarded as the founder of the theory of the biosphere (i.e., the total mass of living organisms, which process and recycle the energy and nutrients available from the environment).[2]
His biosphere theory proposed an important approach to the biosphere as a self-regulating system, which was less known in the West but highly influential in Russian scientific thought.[3]
Vernadsky also developed the concept of the noosphere, the next phase in biospheric evolution where human thought and activity become a major geological force harmonizing humanity's relationship with nature.[4]
G.E. Hutchinson, the influential Yale limnologist, adopted the biogeochemical approach in the late 1930s building on Vernadsky's 1920s work, first referring to Vernadsky in his scientific publications in 1940.[5]
Death
Vladimir Vernadsky died on January 6, 1945, in Moscow, at the age of 81.
