Alexander Sergeevich Davydov was a Soviet and Ukrainian physicist. Davydov graduated from Moscow State University in 1939. In 1963-1990 he was Director of Institute for Theoretical Physics of the Ukrainian Academy of Sciences.[1]

His main contributions were in theory of absorption, scattering and dispersion of the light in molecular crystals. In 1948, he predicted the phenomenon that is known as Davydov splitting. In the period 1958-1960 he developed the theory of collective excited states in spherical and non-spherical nuclei, known as Davydov-Filippov Model and Davydov-Chaban Model.[1]

In 1973, Davydov applied the concept of molecular solitons in order to explain the mechanism of muscle contraction in animals.[2][3][4] He studied theoretically the interaction of intramolecular excitations or excess electrons with autolocal breaking of the translational symmetry. These excitations are now known as Davydov solitons.
