Life

The farmer's son Kell began studying at the St. Petersburg Mining Institute in 1903 . In 1906 he worked on a section of the Donetsk Railway and in 1907 on a section of the St. Petersburg tram . As a topographer of the Russian Geographical Society , he was part of the geological department of Fyodor Pavlovich Ryabushinski's expedition , with which he came to Kamchatka . There he carried out careful geodetic investigations using modern triangulation methods with the use of a phototheodolite from 1908–1911 and used his results to create the first map of the volcanoes of Kamchatka. His atlas of the volcanoes of Kamchatka, published in the late 1920s, is still used today. In 1915 he completed his studies in St. Petersburg.

After completing his studies, Kell worked from 1917 as a lecturer and from 1920 as a professor at the Urals Mining Institute in Yekaterinburg , where he set up the chair for geodesy . In 1923 he returned to the Mining Institute in Petrograd and headed the Chair of Geodesy (until 1953). In addition to teaching, he led the geodetic work of the Geological Committee in Kuzbass (1923-1927), the measurement of the magnetic mountain in the Urals (1926-1927) and later at the Magnitogorsk was built, and the geodetic studies of the Crimea - Landslide station (1931- 1937). In 1930 he published the first Russian handbook for geodesists, surveyors and topographers. In 1936 he applied for a patent for his stereo modulator for easier map drawing on the basis of photo triangulation and defended his doctoral thesis . In 1946 he became a Corresponding Member of the Academy of Sciences of the USSR (AN-SSSR).

From 1947 to 1965, Kell headed the AN-SSSR's Laboratory for Aerial Photography Methods for Geological Studies. In 1948 he received the Order of Lenin . He developed methods for rectifying aerial images and for orienting a flying aircraft in space. He promoted the introduction of the Gauss-Krüger coordinate system in the USSR .

Kells son was the mine separator and rector of the Leningrad Mining Institute Lev Nikolayevich Kell .

The stratovolcano Kell on Kamchatka was named after Kell and in 1966 a mountain in Antarctica was named .
