description Adam Sedgwick Overview

Adam Sedgwick was an English geologist, Anglican priest, and long-serving professor of geology at the University of Cambridge. He established the Cambrian geological system in 1835 from his study of older rock sequences in Wales, while Roderick Murchison defined the neighboring Silurian system; disagreement over their boundary later produced a major stratigraphic controversy. Sedgwick also taught Charles Darwin, although he subsequently opposed Darwin's theory of evolution by natural selection.

Who was Adam Sedgwick?

Adam Sedgwick was a prominent 19th-century British geologist and an Anglican priest who spent his career at Cambridge University. He is considered one of the founders of modern geology for his extensive work classifying ancient rock strata.

What is Adam Sedgwick most famous for in geology?

He is most famous for defining the "Cambrian period" of the geological timescale in 1835. He developed this classification alongside his contemporary and frequent collaborator, Roderick Murchison.

Did Adam Sedgwick have a famous scientific disagreement?

Yes, despite initially working together to map ancient rock formations, Sedgwick and Murchison had a bitter, public dispute over the boundaries of the Cambrian and Silurian periods. The feud was eventually settled by Charles Lapworth, who created the Ordovician period to resolve the overlap.

What was Adam Sedgwick's relationship with Charles Darwin?

Sedgwick was actually Charles Darwin's geology professor at Cambridge and introduced him to the field through a famous field trip to Wales. However, Sedgwick famously opposed Darwin's theory of evolution, strongly criticizing "On the Origin of Species" on both scientific and religious grounds.
