Leonid Maksimovich Brekhovskikh
(1917-2005)
 

Leonid Maksimovich Brekhovskikh
was born in 1917.

In 1939, he graduated from the Physicomathematical faculty of the Perm' State University and, after that, became a post-graduate student of the Lebedev Physical Institute of the Academy of Sciences of the USSR.

In 1941, he received his candidate degree and, in 1947, he became doctor of science.

In 1953, Brekhovskikh was elected correspondent member of the Academy of Sciences of the USSR, and, in 1968, he was elected full member of this academy.

Brekhovskikh is the author of more than 200 scientific publications including 12 monographs, the latter being of fundamental importance for acoustics, radio-wave physics, and oceanology. Some of these monographs determined the development of new branches in acoustics.

L.M.Brekhovskikh carried out extensive theoretical studies of wave propagation in media with a layer-wise inhomogeneity including the sound propagation in the ocean. He was the first to construct a rigid theory of sound propagation in the underwater sound channel. The existence of the underwater sound channel was discovered by Brekhovskikh and his colleagues. This was a most significant discovery in the ocean acoustics. It changed the previously existing notions of the spatial structure of underwater sound fields and provided new possibilities in oceanic explorations.

The results of the long-term studies carried out by Professor Brekhovskikh are summarized in his monograph "Waves in Layered Media". This book received wide recognition from the scientific community.

Brekhovskikh was one of the founders and the first director of the Acoustics Institute of the Academy of Sciences of the USSR. Since 1979 up to the present day, he heads the department of Ocean Acoustics at the Shirshov Institute of Oceanology of the Russian Academy of Sciences.

Brekhovskikh combines his scientific and organizational activities with professorship. Until recently, he headed the department of Physics of Hydrocosmos at the Moscow Institute of Physics and Technology.

In 1970, Brekhovskikh was awarded a Lenin Award for his major contribution to hydroacoustics. As a member of a team working on important scientific and applied problems, he twice received USSR State Awards (in 1951 and 1976).

For his contribution to the Russian science, Leonid Maksimovich Brekhovskikh was awarded three Lenin Orders, an Order of the Red Banner of Labor, and many medals. In 1987, he was given the title of Hero of Socialist Labor.
