Jaroslav Heyrovsky (Heyrovsky) was born December 20, 1890 in Prague, died on March 27, 1967 in the same place.
In 1918 he graduated from the University of Prague. Student B. Brauner. In 1910-13 he studied at the University College London, and in 1913-14 he worked in the same place under the direction of F. Donnan.
Since 1922 extraordinary, with 1926ordinarny Professor of Physical Chemistry of the University of Prague. From 1922 he headed the Institute of Physical Chemistry of the University of Prague. In 1926 he worked at the Sorbonne (Paris). Since 1950 Director of the State polarographic institute in Prague, since 1964 bears his name. Foreign member of the Academy of Sciences of the USSR (1966) and a number of others. Academies.
In 1922 Heyrovsky, exploring the process of electrolysis to the dropping mercury electrode, set the relationship between the reduction and oxidation potentials of the substances and their nature as well as the diffusion current value and the concentration of the substance in the electrolyte, which served as the basis for polarography.
In 1925vmeste with his pupil M. Shikata constructed polarography to automatically record the polarization curves in the voltage and current coordinates. Heyrovsky fully developed polarographic method, theory and technique of polarographic research, for which he received the Nobel Prize (1959).
