Charles Davison (1858–1940) was a renowned British mathematician and seismologist. In this book, which was first published in 1927, Davison provides a historical study regarding the origins of seismology and the key figures in its development. The text was based upon a series of articles which appeared in the Geological Magazine during 1921, although more material was added subsequently. Illustrative figures and notes are incorporated throughout. This book will be of value to anyone with an interest in earthquakes, seismology and the history of science.
