Nicolaus Steno

Nicolaus Steno was a 17th-century scientist and bishop who made important contributions to geology and anatomy. He developed the principles of stratigraphy, which is the study of rock layers, helping us understand Earth's history. Steno observed that fossils in different layers indicated the sequence of events over time. His work laid the foundation for modern techniques in studying the Earth's layers and understanding how fossils relate to geological processes. Despite being a clergyman, his scientific insights significantly advanced our knowledge of natural history and the development of scientific methods.
