Jaroslav Heyrovský: The story of a mercury drop

''Professor Heyrovský. You are the originator of one of the most important methods of contemporary chemical analysis. Your instrument is extremely simple - just falling droplets of mercury - but you and your collaborators have shown that it can be used for the most diverse purposes ... May I ask you to advance and receive the Nobel Prize for Chemistry for this year from the hands of our King'', said professor Arne Ölander, member of the Nobel Committee for Chemistry, in Czech language to the laureate Jaroslav Heyrovský at the award ceremony in the Stockholm Concert Hall on 10th December 1959. The year of 2020 is the year of 130th anniversary of the birth of prof. Jaroslav Heyrovský, the first Czech recipient of the Nobel Prize in Chemistry and 61 years since he received his prize in Stockholm (Sweden).
