Kravkov Sergey Nikolaevich 
(11(23).11.1894 – February 1942)

Soviet hydrograph, arctic explorer. 
Born in St. Petersburg in the family of a native of Ryazan, the famous Russian scientist, the creator of the national pharmacological school, Academician Nikolai Pavlovich Kravkov (buried in St. Petersburg at the Novodevichy Cemetery, the grave was preserved). Kravkov’s mother was the daughter of the famous surgeon E.I. Bogdanovsky (buried in the Tikhvin cemetery of St. Petersburg, in 1936, the ashes were transferred to the Literary bridges of the Volkovsky cemetery, the grave was preserved). It seemed that the young man was destined to be a doctor, but he became a sailor. 
He graduated from the Naval Cadet Corps and was assigned to the Black Sea Fleet, participated in the First World War. In 1914, in the famous battle of Russian battleships with the German cruisers “Geben” and “Breslau” at Cape Sarych on the Black Sea, midshipman Kravkov showed both personal courage and talent as a draftsman. Adjusting the fire of the battleship "Three Saints" from the mast, he performed historical watercolor sketches of the battle, published in the Sea Collection magazine, under the whistle of the fragments. Later they were printed in one of the maritime textbooks and are still of historical value. For participation in this battle Kravkov was awarded the Order of St.Anna of the 4th degree.

In 1917  Kravkov graduated from navigator classes and received the title of navigator of the first category. 
In 1919  he went to the Pacific Ocean on the minesweeper "Jerusalem", served in the Siberian military flotilla, was the flagship navigator of the headquarters of the naval forces of the Far East. Since 1923  his life has been associated with work in the Arctic Ocean. In 1923–1926 Kravkov explored the northern seas as part of Ubekosibir, in 1930-1932  performed hydrographic works in the Taz and Ob Bay, completed sketches for the first lot of the Ob Bay. 
Subsequently, Kravkov specialized in astronomical works, having visited many parts of the Northern Sea Route. The astro points in Minin's skerries, Gydan Bay, on the coast of the East Siberian Sea, served for a long time as the basis of maps of those places. During his observations in the Lena Delta in the winter of 1940, he froze his legs and hands severely. Doctors at the Tiksin hospital hardly saved his life, but his hands and feet had to be amputated. Becoming disabled, Kravkov worked in the scientific archive of Polar Hydrography. He refused to evacuate from Leningrad, firmly believing that his native city would not be surrendered to the enemy.

For many years the professor of the Ryazan Medical Institute, Dinara Uzbekova, dealt with the history of the Kravkov family, from an article in the Ryazan newspaper “Priokskaya” dated May 27, 1994, you can learn about the circumstances of Kravkov’s death: which Sergei Nikolayevich, his mother and sister were registered. In the column “Departure” I saw a terrible record: in February 1942, all three Kravkovs died of hunger and cold”.

From the besieged memory book, we managed to find out that Kravkov was buried at the Serafimov cemetery. The grave is not preserved. 
An island in the Mon island group of the Nordensheld archipelago in the Kara Sea. Apparently, it was discovered in 1893 by the expedition of F. Nansen and approximately mapped on a map without a name. Named in 1933 V.I. Vorobjev, who determined his exact position.
