Biography
The father of the scientist, a graduate of the Paris Polytechnic School, was demobilized from the army and aimed at creating a society of railways of the North.
Henri Begen entered the Higher Normal School in 1894 with Paul Montel , Henri Lebesgue , Paul Langevin , Charles Peggy . He headed the department of rational and applied mechanics in 1924 after Albert Chatel . The next year he headed the department of differential and integral calculus after Jean Chazy .
He taught a preparatory course for students at the Maritime School ( l'École navale , 1899–1908), then taught mechanics at this school (1908–1921).
In 1929, he received the title of professor in Paris, and soon began to work at the Paris Polytechnic School . Together with Gaston Julia, he wrote a book of exercises in mechanics in 1930-1931.
In 1941 , when Begen during the occupation could not carry out research on guidance systems, he addressed the issues of working internal combustion engines on poor fuels, gas and vegetable oil.
In 1946, Henri Beguin was elected a member of the French Academy of Sciences.
Widowed, he remarried one of his students in Lille.
Scientific activity
An outstanding theoretician, Henri Begen actively contributed to the engineers in the implementation of their inventions. In Lille, he was offered a high-precision gyrocompass capable of holding a fixed direction in space, which is necessary for automatic piloting in aviation and maritime navigation. He carried out the refinement of the gyrostatic sextant and other devices necessary for targeted bombing.
An important contribution of A. Begen to mechanics was the concept of servo-links introduced by him in 1922 [1] (independently - and somewhat earlier - Ya. I. Grdina came to a similar concept of “volitional connections”). Over time, it has found numerous applications in the theory of automatic control , robotics , computational mechanics [2] .
