Abstract
The article commemorates five centenaries of Czech analytical chemistry associated with the Faculty of Sci-ence, Charles University. Above all, a hundred years passed since the discovery of polarography by Jaroslav Heyrovsky.
The method, the principle of which he discov-ered in February 1922, subsequently gave rise to many electroanalytical methods, which still affect many fields of human activity. The second centenary is closely connected with the name of Prof.
Heyrovsky, namely, the first publi-cation of this discovery ever, in Chemicke listy journal in October 1922. The remaining anniversaries are personal, being associated with a hundred years since the birth of three outstanding Czech analytical chemists, Jaroslav Zyka, Vaclav Suk, and Miroslav Malat.
Their most im-portant contributions to the development of chemistry are reviewed.
