Sergei Pietrovich Kapitsa
b. February 14, 1928 in Cambridge, Soviet and Russian physicist, the son of the Nobel Prize Kapitza, and
the grandson of A. N. Krylov, the Russian mathematician and shipbuilder,
and the great-nephew of the famous French biochemist Henry Victor / Victor Henri, Krylov - on his mother side, Anna Alekseevna.
The great-grandson of a geographer I. I. Stebnicki that is Ierome Stebnicki / Hieronim Stebnicki,
the elder brother of A. P. Kapitsa.

Father - Peter Leonidovich Kapitsa - the famous physicist and Nobel Prize winner,
mother - Anna A. Krylov, the daughter of Alexei Krylov, Russian ship builder, an expert in the field of mechanics, mathematics.

Above named Krylov, Alexey / Alexei Krylov, b. in August 1863, and in 1878 he entered the Naval Academy, he graduated with honors in 1884, worked in the Hydrographic Office of P. Kolong, study of the magnetic deviation, in 1887 Krylov moved to
(since 1892 the Duflon and Konstantynowicz Company in St Petersburg; before 1892 Duflon acted in the Breguet Company in Petersburg owned by the Brown family from London)
the Franco - Russian plant, and then continued his studies at the shipbuilding department of the Nicholas Naval Academy.
1890 he remained at the Academy. According to the memoirs of Krylov, since 1887, his specialty was ship-building, the application of mathematics to various issues of maritime affairs and expanded the theory of William Froude, 1896 he was elected a member of the British Society of Naval Architects, proposed the gyroscopic damping roll.
His daughter Anna, became the wife of Kapitza.
Since 1900, Krylov cooperates with Stepan Osipovich Makarov, Admiral and scientist and shipbuilder.

Acc. to an Academician A. N. Krylov / Kriloff, 'My memories' on Stefan Drzewiecki = Stepan Karlovic Drzewiecki:
It was a talented engineer and inventor, with whom Krylov was friendly to April 1938. He knew Drzewiecki in November 1878, at age 15, being at the Naval College
(Admiral Gregory I. Butakov died in the summer of 1882, as a teacher of the fleet, with an architect I. G. Bubnov and Captain 2nd rank M. N. Beklemishev [see Duflon and Konstantynowicz Company], and he cooperated on the project of submarine 'Dolphi').
Krylov met Drzewiecki many times in the technical society. In January 1886 was organized the first Electrical Exhibition. At this exhibition participated main hydrographic office, with the last sample of a compass 'de Kolong' and also
participated a Parisian company 'Breguet', with two instruments invented by the French Navy admiral Fournier: among others dromoskop.
I. A. Shestakov and Main Hydrographic office was instructed to investigate these devices (I. P. de Kolong, Lieutenant N. M. Yakovlev and Krylov who met Drzewiecki). This work was later published in 'Sea collection'.

Krylov soon teamed up with the Petersburg department of the company 'Breguet', on dromoskop. Krylov then met with the engineer Dyuflon, a representative of 'Breguet', Swiss, friend of Drzewiecki and of Apolon Konstantynowicz.

Drzewiecki occupied a luxury apartment of the house No 6 Admiralty Street. In the evenings, guests of Drzewiecki were brothers
Paul and Peter Solomonovich Martynov,
Dyuflon
and botanist Professor Poirot,
K. E. Makovsky and
the Serbian Prince Karageorgievich, who formerly served in the French Foreign Legion,
mainly for scientific or technical topics, flying airplanes on a theory of Drzewiecki (in April 1884 he published it and the chief inspector Rear Admiral Loschinsky invited Krylov to resolve this issue).

Drzewiecki acc. to his friend from Moscow, Goujon (remembering on the later system of J. Roy / Rey) and Dyuflon / Duflon, was noble, of an ancient clan of Poles, who owned large estates in the Volyn province, land in Odessa, orchard houses in Warsaw, etc. Drzewiecki had an extensive knowledge of the St. Petersburg nobility. His parents were living in Paris, where he was educated at home, at the Lycee St. Barbe, and the Central Engineering College. Among his companions was Eifel (aerodynamic research).

In 1873, Drzewiecki was at Vienna World Exhibition. When Drzewiecki moved to St. Petersburg, he turned to the famous Brouwer, at the Pulkovo Observatory and to the War Minister P. S. Rakovsky (construction of 50 boats, with the payment of 100.000 rubles for Drzewiecki).
Drzewiecki, received one hundred thousand, and went to Italy.
Summer 1886 Drzewiecki went to Turkestan, to General Annenkov (the Trans-Caspian railway from Krasnovodsk to Samarkand with a huge bridge across the Amu Darya in Chardzhui).
The following summer, he went to Egypt, to Aswan. 1887 he calls Krylov to show a sketch of a submarine and gone to Grand Duke General Admiral Alexei Alexandrovich with this project to develop a submarine.

In 1888 Krylov was enrolled at the Shipbuilding Division of the Naval Academy, graduated it in 1890. At this time, Drzewiecki went to Paris. 1892 met with Krylov, on the development of the submarine, and together come to Paris. The Marine Technical Committee (boat steam engines, internal combustion engines, and then diesels) cooperated with Drzewiecki because he had an extensive knowledge of French naval engineers and brought Krylov into this world. In 1897 Drzewiecki invented a special type of destroyer for the Naval Ministry, and again asked Krylov to work with him in Paris. The project was adopted by the Technical Committee. In 1892 was the Dreyfus affair and Drzewiecki was not at home, back to St. Petersburg. Around 1905 Drzewiecki developed an original theory of propellers.
1909 to 1914 every time Krylov visited Drzewiecki in Paris, last time met with him 1925 to 1927, when Krylov was abroad for 'Neftesindikat' and 'Soviet oil'.
Stefan Drzewiecki died in April 1938.

His father, Ivan, according to family legend, was a descendant of Cossacks.
Before moving to St. Petersburg, he was Professor of Economics in Kiev. In St. Petersburg, he served as a privy councilor.
His mother, Anna Petrovna nee Konstantynowicz / Konstantinovich, was a Polish noblewoman.

Vladimir Vernadsky was a cousin of the Russian writer Vladimir Korolenko.

Above named Konstantinov, Boris Pavlovich or Borys Konstantinovich / Borys Konstantynowicz, the son of Pawel Konstantynowicz, b. 1910 in St. Petersburg.
Soviet physicist and Vice - President of the Academy of Sciences of the USSR.
Father Paul Fedoseevich Konstantinov / or Pavel Konstantinovich, b. 1874, in 1888 went to St. Petersburg,
mother - Agrippina Petrovna Konstantinov, b. 1876 nee Smirnov, gave birth to eight sons and four daughters;
Boris Konstantynowicz in 1916 was sent to a private elementary school, where he studied until the end of 1917; in early 1918 the family moved to the home of parents in the village. In 1919 his father died. In the winter 1920 - 1921 he lived and studied in St. Petersburg. Autumn of 1924 the family moved to Leningrad. At this time, at the Physico-Technical Institute worked older brother of Boris -
Alexander Pavlovich Konstantinov (1895 - 1945, repressioned, was posthumously rehabilitated) or maybe Aleksander Konstantynowicz, who became one of the largest radio technicians, radiophysicist
and create a variety of radio-electronic equipment (with Bonch - Bruevich) and contributed to the development of television - suggested a way to narrow band television signals, has developed a mosaic photocathodes for the television camera tubes of the 1930s television transmission.
He was a member of the laboratory of L. S. Theremin: an alarm systems of banks and museums.

A. Konstantinov was an electrician in this protective system - 1909. In 1924 he created the radio-electronic equipment to determine the difference in longitude of Greenwich and Pulkovo Astronomical Observatory,
in 1928 to 1930 with his brother has developed radio - protective signaling processes of government vaults. They invented electric seismographs have been used successfully for mineral exploration.
He studied at the Physics and Mechanics of the Leningrad Polytechnic Institute 1926 - 1929 and was expelled from this Polytechnic after fourth years for the non-proletarian origin, but was able to continue working in science through the application of Ioffe.
He worked as a laboratory assistant, senior laboratory assistant at the Physical - Technical Institute, 1935 - 1937 in the department of electro - acoustics of the Leningrad Institute, (in 1937 Konstantinovich Aleksandr Pavlovich was wrongly arrested and died in the dungeons of the NKVD)
but 1937 - 1940 he headed a laboratory of the Research Institute of the music industry and acoustics for the needs of defense - but we need check this data.
His brother Boris Pavlovich Konstantinovich or Konstantinov was born in St. Petersburg in 1910, acc. to his autobiography, written an excellent literary language. In 1924 Konstantinov moved to Leningrad, because at the State Physical - Technical Institute of the X-ray worked his older brother, Alexander P. Konstantinovich. Since 1927 he started working at the laboratory of D. A. Rozhanski as a physicist and was student of Physics and Mechanics Faculty of the Polytechnic Institute.
A few details on Boris Konstantinov / Borys Konstantinovich:
Konstantinov Boris Pavlovich or Konstantinovich B. P. born on 23 June / 6 July 1910 in St. Petersburg and died July 1969. In 1927-35 and since 1940 has worked in the Physical - Technical Institute of the Academy of Sciences of the USSR, 1957-67 director, in 1937-40 at the Research Institute of the music industry (like his brother?!).
"In the 90's of last century, was opened part of the work on the nuclear problem, and as a result over the past half ten years, there are many books and publications devoted to the development of research on the nuclear problem in the USSR and Russia... There was a series of films about the secret physicists ... I. V. Kurchatov, Y. B. Chariton, Ya. Zel'dovich, A. D. Sakharov, I. E. Tamm, V. L. Ginzburg and others in the work on the atomic problem,
but the role of B. P. Konstantinov reflected very sparingly. This is despite the fact that over the carried out his work, he was awarded the title of Hero of Socialist Labor, was elected to the Academy and became director Physico - Technical Institute, vice - president of the Academy of Sciences of the USSR, it is named after him the Institute of Nuclear Physics Gatchina and the largest chemical plant in Kirov...".

"...B. P. Konstantinov / Konstantynowicz is one of the founders of the school of nuclear physicists.
In 1945, the Physics and Mechanics Department opened the country's first training in the Department of Nuclear Physics (Department of Technical Physics). The first head of the department was A. F. Ioffe, but after 2 years it was headed by B. P. Konstantinov / Konstantynowicz, who since 1945 has combined his academic work at PTI with teaching at the LPI...".

"The Petersburg Nuclear Physics Institute (PNPI) is one of four nuclear physics centers within the National Research Center 'Kurchatov Institute' / NRC 'Kurchatov Institute'. PNPI bears the name of Academician B. P. Konstantinov ...
Director of the Ioffe Physical Technical Institute of the USSR Academy of Sciences, vice president of the Academy of Sciences...".

At the beginning in accordance with the Decision of the Council of People's Commissars of the USSR in 1942 which was composed of the Commissariat of Communications was formed Military restorative management for all military telephones and telegraphs and broadcasting units, radio and postal enterprises on the territory liberated from the German.
B. P. Konstantinovich / Konstantynowicz Borys / Konstantinov was working for this management (at the Petersburg Nuclear Institut as Head of Laboratory 1943 - 1957, for the Federal Agency for Special Construction / Spetsstroy Russia).
1951 established the Office building number 565 as a part of Ministry of Internal Affairs of the USSR - successor of the General Directorate of Special Construction.
In 1953 in Leningrad was organized management for the construction of the air defense system.
