Neupokoev Konstantin Konstantinovich 
(11(23).09.1884–19.01.1924)

Hydrographer, explorer of the Arctic. 
Born in St. Petersburg in the hereditary maritime family. For him, the fate of the naval officer was predetermined by the old Catherine’s decree, which prescribed all the men of the Neupokhaev family to serve in the navy. Neupokoev's father, Konstantin Mikhailovich, served under the leadership of M.F. Reineke was shooting the Baltic Sea, where six cans are named after him. He retired with the rank of Major General of the Navy Naval Corps. 
Of the twelve children of Konstantin Mikhailovich, four sons graduated from the Naval Cadet Corps. 
The eldest, Vladimir, in 1894 as part of the crew of the cruiser "Herald (Vestnik)" participated in the shooting of the coast of the Kola Peninsula in 1900-1901. made meteorological and hydrographic observations during the cruises of "the Yermak" icebreaker under the direction of S.О. Makarov, explored the Pacific Ocean. From the Russo-Japanese War of 1904–1905 left with a wound and the Order of St. Anne 3 degrees, in 1905 he was dismissed from service with the rank of captain 2 rank. He is rightfully considered the founder of the Vladivostok Naval School, which he managed until his death in 1912. 
Leonid was shot dead in 1905 during an uprising on the battleship Potemkin, a well-known Soviet people sailor Matyushenko. 
The youngest, Dmitry, in 1908 served as a mine officer in the Russian squadron that assisted victims of the Messina earthquake, was awarded the Italian silver medal. His military achievements during the First World War were marked by two Orders of St. Anna and the Order of St. Vladimir, 4 degrees. 
Not only the old decree, but to a greater extent his own ardent desire led Constantine to the Marine Corps, where his brilliant abilities immediately manifested themselves, especially in mathematics. One of the best he graduated from the corps, having received a prize for them for academic success. P.S. Nakhimov. 
Upon graduation in 1905  Neupokoev was sent to the Far East, where the Russian-Japanese war was still going on. He began service on warships, and after the completion of military operations in the position of senior navigator of the "Shilka" transport, he made an inventory of the Kwantung Peninsula and the eastern coast of Kamchatka, carried out measurements in the Far Eastern seas. Swimming in the little-studied and difficult to navigate places became for him an excellent maritime school. Having chosen the navigator's business from numerous marine specialties, he achieved great success, becoming in a short time one of the best navigators in the Far East. 
The most important stage in the life of Neupokoev was participation in the hydrographic expedition of the Arctic Ocean. He turned out to be one of the few officers who took part in all five voyages of the expedition, having gone through all its sorrows and rightfully dividing all its successes and achievements. 
Neupokoev was appointed one of the assistants to the chief of the expedition and the senior navigator of the "Vaigach" icebreaking steamer, where he also supervised hydrographic work while performing navigator duties. These works of the expedition, due to the specifics of the tasks facing it, were not ordinary, not systematic. Including most of the difficulties of hydrographic work in the Arctic seas, at the same time they required a great deal of navigator experience and the ability to understand the most complicated situation. According to colleagues in this regard, Neupokoev stood out sharply from among his comrades. By virtue of his abilities, propensity to analyze, natural talent in assessing the distribution of ice, the ability to determine his location, he was absolutely indispensable. His friend N.I. Eugenov wrote: “I, who had sailed with him on the Expedition for three years, personally had to marvel at how calmly, with what endurance Konstantin Konstantinovich was guiding the ship. In 1915 the vessels of the Expedition "Taimyr" and "Vaigach" for release from the ice shackles for wintering owe their successful exit to clean water in the future to a large extent K.K-chu. Involuntarily, a picture of the brilliant maneuvers of the Vaigach in the Mathisen Strait and the withdrawal of vessels from the Dawn of the Fram Strait amid heavy ice further west come up before my eyes. And all this is because K.K. Neupokoev was on the "Vaigach". 

The role of Neupokoev is great in the scientific achievements of the expedition. They produced a marine inventory with "Vaigach". Together with L.V. Sakharov, he developed the first scheme of surface currents for the western part of the Chukchi Sea, made a huge contribution to hydrographic research, processing of cartographic materials and their subsequent publication. Written by Neupokoev and later published “Materials on the Siberian Sea Locations” were valuable and for a long time the only published material of the expedition. And, finally, Neupokoev along with N.I. Evgenov on Vaigach and L.M. Starokadomsky on the "Taimyr" September 3, 1913 first saw the Northern Earth.

Possessing excellent professional qualities, being a seaman by vocation, Neupokoev, in the opinion of his comrades, was distinguished by his calmness, prudence, and kindheartedness towards people. For his research, he was awarded the Order of St. Stanislav 2 degrees. 
In 1916–1918 Neupokoev commanded the Vaigach and the powerful icebreaker Svyatogor (Krasin). After the revolution, he appealed to the command of the Soviet naval forces in Arkhangelsk with a proposal to organize a hydrographic expedition from Arkhangelsk to the mouth of the Lena. The key to successful implementation of this project, in his opinion, was the experience of navigation in the hydrographic expedition of the Arctic Ocean in 1910–1915. For the work, he asked the steamer "Hoarfrost" with a team of 15 people. Permission was obtained, preparations were well under way, but all plans were frustrated by the intervention. 
After the end of the civil war, Neupokoev led the Ob-Yenisei detachment of the famous Kars expedition of 1920 (the bread expedition). During June – July, the detachment conducted hydrographic works and an inventory of the mouth areas of the Ob and Yenisei. The measurements of the Yenisei's throat were made, and the icebreaking steamer “Vaigach” sitting on the pitfalls was examined. Since 1920, the Neupokoev detachment has developed its activities in the areas of the Ob Bay, the Yenisei Bay, the lower reaches of the Ob and the Yenisei, providing Kara expeditions, which are vital for the country's economy. Hydrographic work under the leadership of Neupokoev was continued in the Ob-Yenisei region in 1921. 
Taking into account the scope and importance of the tasks facing the Ob-Yenisei detachment, in 1922 it was reorganized into Ubekosibir, Neupokoi became its first head. In the summer Neupokoev personally overtook the Metel hydrographic vessel from Petrograd on the Yenisei. It was the first foreign campaign of the courts of the young Soviet Russia, about which now very few people know. 
The scale of the personality of Neupokoev, as a person and a specialist, allowed him to become a leader capable of solving strategic tasks that go beyond navigation. He was a participant in a number of meetings that had a wide interdepartmental nature. In 1923 Neupokoev was assigned the task of developing and building marine lighters intended for navigation on the Northern Sea Route. He sought to expand the scope of activities Ubekosibiri. In December 1923 the Polar Commission of the USSR Academy of Sciences heard a report by Neupokoev on the possibilities of Lena coastal navigation. 
Neupokoev's colleagues, friends, all who had to deal with him, in addition to the highest professionalism of Konstantin Konstantinovich noted his extreme modesty, compassion, goodwill and decency. As N.I. Eugenov, “being a very modest man, he did not receive, perhaps, that fame in wide circles, on which he was entitled to count, although among the leaders of the north, the name of K.K. Neupokoeva always enjoyed great weight. Meeting with him on the shore, in a private conversation it was difficult to imagine that you were a famous, brave explorer and a brilliant sailor”.  
Neupokoev's tireless work, full of energy, new ideas and plans, was tragically interrupted after an unsuccessful operation of appendicitis. He left in the prime of life, having failed to do much and left his wife with three small children (the younger one, also named Konstantin, was born six weeks after the death of his father). I was lucky enough to talk with Konstantinov Konstantinovich Neupokoev Jr. shortly before his death, visit his house, get typewritten materials about the Neupokoevs, drink a glass of cognac with him.

After the death of Neupokoeva, for many years  vessel "Neupokoev" led the hydrographic survey in the south-eastern part of the Kara Sea.
He was buried in Petrograd at Shuvalovskoye cemetery. The grave, unfortunately, was not preserved. 
The island and the spit in Gydan Bay. Neupokoev established his insular position in 1921. Named Hydrographic Office in the 1930s. 
Cape and lagoon in the south-west of Bolshevik Island. The cape was discovered in 1914 by a hydrographic expedition of the Arctic Ocean. Named later at the request of the head of Ubekosibiri Timofeevskiy and hydrograph Morozov. Laguna received its name from the cape in the 1950s. 
The bay between the gulfs of Rusanov and Sedov on the east coast of the northern island of Novaya Zemlya. Opened in 1910 V.A. Rusanov and named after Ilya Vylka. The name did not stick. The modern name was given in 1925 by the expedition of the Institute for the Study of the North on the ship "Elding". 
Bay on the island of Transfiguration in the Laptev Sea. Named in 1914, the hydrographic expedition of the Arctic Ocean.
