Archibald Geikie

Archibald Geikie (1835–1924) was a Scottish geologist and science writer who directed the Geological Survey of Great Britain and Ireland and served as president of the Royal Society.

Roderick Murchison: A Scottish geologist who led the Geological Survey of Great Britain and Ireland and helped establish Silurian stratigraphy. Murchison recruited Geikie to the Geological Survey and shaped his early career.
Geological Survey of Great Britain and Ireland: The government organization that mapped and investigated the geology of Great Britain and Ireland. Geikie’s long service and directorship centered on this national geological institution.
Stratigraphy: The study of rock layers, their relationships, and their sequence through geological time. Geikie’s survey and historical geology depended on reading the order and character of strata.
Royal Society: The United Kingdom’s national academy of sciences, founded in 1660. Geikie’s presidency from 1903 to 1908 marked the culmination of his scientific leadership.
James Geikie: A Scottish geologist who studied glaciation and succeeded his brother Archibald as director of the Geological Survey of Scotland. Archibald’s younger brother was a geologist and a close scientific collaborator.
Geological mapping: The representation of rock types, structures, and geological boundaries on maps. Survey work under Geikie relied on mapping to turn field observations into usable records.
Uniformitarianism: The principle that geological processes observed today also operated in the past, though their rates may vary. Geikie used present-day processes to explain the formation of ancient landscapes.
Geological Survey of Great Britain: The government body that systematically mapped the geology and mineral resources of Great Britain. As director-general, Geikie oversaw the survey’s expansion and its scientific work.
Charles Lyell: A Scottish geologist whose theory of uniform geological processes reshaped nineteenth-century geology. Lyell’s gradualist approach informed the geological tradition in which Geikie worked.
The Scenery of Scotland: Archibald Geikie’s 1865 book explaining Scotland’s landscapes through their geological history. This book exemplifies Geikie’s effort to connect geological structure with visible scenery.
