Gerard De Geer – a pioneer in Quaternary geology in
Scandinavia
The paper presents a pioneer in Quaternary geology, both
internationally and in Scandinavia – the Swedish geologist and professor Gerard
De Geer (1858–1943). This is done, first by highlighting one of his most
important contributions to science – the varve chronology – a method he used to
describe the Weichselian land–ice recession over Scandinavia, and secondly by
the re-publication of a summary article on Gerard De Geer’s early scientific
achievement in 1881–1906 related to the Baltic Sea geology, written by his
wife, Ebba Hult De Geer.
