| Zahálka, Čeněk Dr. Tech. Sci., Dr. h. c.
Geologist and teacher. From his youth he was interested in geology and mineralogy. After completing the Czech College of Technology he had teaching qualification for mathematics and descriptive geometry and, since 1878, was teacher at secondary school, Teachers College in Jičín, and later at Commercial College in Tábor. Since 1886, he taught at a variety of high schools in Roudnice nad Labem, where he lived till 1908. His scientific activities are closely related to studies of the Bohemian Cretaceous system. He became interested in this subject during his studies at the Prague Polytechnic College where he was student of professor J. Krejčí and professor A. Frič, who also investigated the Bohemian Cretaceous. He devoted almost sixty years of his life to this topic considering stratigraphy, petrography, and paleontology. He introduced new stratigraphic division of the Bohemian Cretaceous and correlated it with the West European Cretaceous. He was also interested in pedology, being considered pioneer of pedological studies in Bohemia. He investigated Cretaceous sponges, some yet unknown or newly described, in the Roudnice environs. Shortly before outbreak of World War One he completed his largest monograph 'Útvar křídový v Českém Středohoří' (Cretaceous System in the České Středohoří Mountains). The text was accompanied with tables and geological map at a scale of 1 : 25 000, which he published in 1914 (author’s edition). Other publications dealing with Cretaceous system of the České středohoří Mountains include 'Severočeský útvar křídový z Rudohoří až po Ještěd' (North Bohemian Cretaceous System from Krušné hory Mountains up to Ještěd Mountains, 1916), 'Východočeský útvar křídový, část jižní' (The East Bohemian Cretaceous, southern part, 1918) and 'Východočeský útvar křídový, část severní a Slezsko' (The East Bohemian Cretaceous, northern part, and Silesia, 1921). He also accumulated large collection of Cretaceous minerals and fossils.
