Jaroslav Heyrovský (1890 – 1967) was a Czech chemist, inventor of the polarographic method and recipient of the Nobel prize for chemistry in 1959.

He was born in Prague, and already during his studies at a grammer school he was mainly interested in chemistry, physics and mathematics. He started his university studies at the Charles University in Prague but after two years continued his studies at the University College in London under Professor Sir William Ramsay. He ended his studies in 1913 as B.Sc. During his cooperation with Professor Donnan he took a lively interest in electrochemistry.

Later he continued in his studies and took his Ph.D. degree in 1918 in Prague and D.Sc. in 1923 in London. He started his university career at the Charles University in Prague where he was soon promoted from an assistant to the University’s Professor of Physical chemistry.

In his scientific career Heyrovský engaged particularly in polarography for which he received the Nobel prize for chemistry on 10 December 1959. Jaroslav Heyrovský died in 1967 and was buried in the Vyšehrad cemetery in Prague. In 1982, asteroid 3069 was named Heyrovský in his honour.

The obverse side of the medal features the portrait of Jaroslav Heyrovský, Nobel prize winner for polarography and years of his birth and death.

On the reverse side the bust of Alfréd Nobel – who initiated the founding of the Nobel Prize in his will – is placed above Heyrovský’s invention - the polarograph.
