Mordovin Konstantin Pavlovich 
(01.08.1870–03.10.1914)

Russian hydrograph, Major General Hydrograph Corps, Arctic explorer. 
Born in St. Petersburg in the family of a naval officer. In 1883 he entered the Maritime School, which he graduated in 1889 with the first graduation.For his academic achievements, his name was put on a marble board and given a prize of 300 rubles. 
Mordovin began his service in the Far East, and after returning to St. Petersburg he took an academic course in hydrographic sciences, which determined his further, unfortunately, short life. 
The consolidation of theoretical knowledge was his participation in the hydrographic expedition of the Arctic Ocean of 1894–1895 under the command of A.I. Vilkitsky. In this difficult and interesting journey, Mordovin helped the chief to conduct astronomical and geodesic observations and process the materials obtained. For his studies, he was awarded the Order of St. Anna, 3 degrees. After this expedition, he finally connected himself with hydrography, using every opportunity to improve his professional level, including work in the editorial staff of the Maritime Collection and teaching in the Naval Cadet Corps. 
Mordovin actively worked in the Imperial Russian Geographical Society, where until his death he was secretary of the Cartographic Commission. At the XI International Shipping Congress, held in St. Petersburg in 1908, he gave a report on the hydrographic survey of the seas, in which the state of the problem was comprehensively and deeply analyzed. This report later served as the basis for the preparation of the program and the questions posed by the Head of Hydrographic Administration for discussion at the first Maritime International Conference on the Safety of Navigation, held in St. Petersburg in spring 1912. 
 Mordovin's pen owns many works on hydrography, including the course "Sea inventory", which exceeded many foreign works of this kind.

In 1913  in the “Notes on Hydrography”, Mordovin wrote an insightful article dedicated to the memory of A.I. Vilkitsky. In less than two years, he himself passed away in the prime of his creative power. In the obituary of Yu.M. Shokalsky wrote: “... Much has been done by him, but even more could have been done if insufficiently good health did not distract him so often from his work, especially in recent years, that is, when he could do a lot while being completely the strength of their abilities .... The circle of people who knew Konstantin Pavlovich is not particularly numerous, but everyone knew him this way and - the best and the only thing left after people - the memory of his beautiful moral character, will remain among us who worked with the deceased”.  
He died in Petrograd, buried in the Smolensk Orthodox cemetery. The grave was found thanks to Vyacheslav Savitsky, the head of the search group of the "Beloye Delo" research center.
