Krylov Alexey Nikolaevich 
(03(15).08.1863–26.10.1945)

An outstanding Russian scientist, shipbuilder, academician, Hero of Socialist Labor. 
Born in the village of Visyaga, Alatyrsky district, Simbirsk province (now the village of Krylovo, Poretsky district, Chuvashia) in the family of an artillery officer. His father was educated at public expense, as the son of a veteran wounded at Borodino. 
In 1878 Krylov entered the Marine School, which he graduated with honors in 1884 and began work in the compass workshop of the Hydrographic Department under the leadership of I.P. Kolong, where he investigated the deviation of magnetic compasses. The theory of magnetic and gyrocompass went through his whole life. Much later, in 1938-1940. He published a number of papers in which he gave a full account of the theory of magnetic compass deviation, investigated the theory of gyroscopic compasses, and developed a theory of the influence of ship’s rolling on compass readings. In 1941, these studies were awarded the Stalin Prize. 
In 1887, Krylov moved to the Franco-Russian factory, and then continued his studies at the shipbuilding department of the Maritime Academy.After completing the course in 1890, he stayed at the academy, where he conducted practical classes in mathematics, and later gave a course in the theory of the ship. 
In the 1890s, Krylov's Theory of Ship Rocking, for which in 1898 he, the first of foreigners, was awarded the gold medal of the British Society of Ship Engineers, gained world renown.

Krylov with his daughter Anna, who later became the wife of academician P.L. Kapitsa, actively collaborated with S.O. Makarov, working on the problem of the buoyancy of the ship. The results of this work soon became classical and are still widely used in the world. Many years later, Krylov wrote about Makarov's early ideas on combating the heel or trim of a damaged ship by flooding intact compartments. It seemed to sea officials a lot of rubbish, and it took 35 years to convince them of the correctness and great practical significance of the ideas of the 22-year-old Makarov. 
Krylov was a talented fleet consultant. He himself noted that his advice saved the government more than the cost of the most modern dreadnought. He was always famous for his sharp tongue, and his apt responses to the government and the Duma became legends. 
In 1916 Krylov headed the Main Physical Observatory and the Main Military Meteorological Department. In 1917 he was appointed director of the Physics Laboratory of the Academy of Sciences, later the head of the Maritime Academy. 
After the revolution, Krylov handed over all the ships to the Soviet government and continued to work on the development of the fleet. In 1921 he was sent to London as a government representative for the restoration of foreign scientific relations of the country. In 1927, he returned to the Soviet Union. 
Krylov is famous for his work on hydrodynamics, including the theory of ship movement in shallow water, he has written about 300 books and articles that cover a wide range of human knowledge, including shipbuilding, magnetism, artillery, mathematics, astronomy and geodesy. Its famous flood tables are widely used.

The activity of Krylov in the pre-revolutionary period was marked by the Orders of St. Anna of 1 and 2 degrees, St. Stanislav of 1 , 2 and 3 degrees, St. Vladimir of 2 , 3 and 4 degrees. 
He died in Leningrad, was buried in Volkov's Literary gangways of the Volkov cemetery near I.P. Pavlov and D.I. Mendeleev. Stele with a bas-relief portrait.
