Richard Oldham

Richard Oldham was an influential geologist and seismologist known for his pioneering work in understanding the Earth's interior. In the early 20th century, he played a key role in studying seismic waves generated by earthquakes, which revealed important information about the Earth's layered structure. Oldham is particularly noted for discovering the Earth's core, proposing it was composed of molten iron based on how seismic waves traveled through the planet. His research significantly advanced our knowledge of geology and seismology, helping us understand the dynamic processes that shape our planet.
