William Smith

William Smith was an English geologist known as the "Father of English Geology." In the early 19th century, he created the first nationwide geological map of England, which demonstrated how different layers of rock could be used to identify the age of geological formations. Smith’s innovative work laid the groundwork for modern geology and stratigraphy, showing that fossil content within rock layers could help determine their relative ages. His contributions significantly advanced our understanding of Earth's history and the processes that shape it, making him a key figure in the development of geological science.
