origin
Helmersen was a member of the noble family of Helmersen . His parents were Russian State Councilor Peter von Helmersen (1776-1860) and his wife Auguste von Sivers (1779-1863). His brother Alexander (1797-1850) became a Russian lieutenant general and director of the cadet corps, his brother Paul (1801-1894) was a high school professor and his sister Anna was married to the professor and explorer Emil Lenz (1804-1865).
Life
He grew up on his father's estate Dückershof. In 1826 he undertook a geological expedition to the Urals together with Ernst Reinhold Hofmann and explored the Southern Urals in 1828/29. From 1831 to 1832 he studied petrefacts in Bonn before traveling to the Urals, the Kyrgyz Steppes and the Altai from 1833 to 1836 . From 1838 to 1863 he worked as a professor of geology at the Berginstitut in Saint Petersburg , which he converted from 1865 to 1872 as director to a free academic institution.
When exploring large areas of Russia , his main focus was on the detection and development of fossil fuels ; He also looked for diluvial peat deposits and amber formations . In 1841 he worked out the first general map of the mountain formations of European Russia and thus created the first geological map of this region.
In 1829 he accompanied Alexander von Humboldt on a journey through Russia and Siberia .
Between two expeditions to the Urals, he traveled to the Altai in the spring of 1834 via Omsk and Barnaul . The first scientific description and recording of Lake Teletsk are due to this trip . He drove the lake lengthways, took height and temperature measurements, drew a precise picture of the mountain forest banks and gave the first more precise descriptions of the residents.
In 1839, together with Karl Ernst von Baer, he founded the first series of natural science books in Russia, the "Contributions to Knowledge of the Russian Empire" (Petersburg 1839–1900, a total of 45 volumes / parts), in which many of his publications appeared.
In 1847 he became a corresponding member of the Society for the History and Archeology of the Baltic Provinces of Russia .
He was a member of the Imperial Science Academy in St. Petersburg and founded the " Russian Geological Committee " in 1882, of which he was the first chairman.
