John Wesley Judd was a British geologist, born in 1840 and died in 1916. He studied at the Royal School of Mines, later joined the Geological Survey of England and Wales, and went on to become a respected teacher and scientific leader.
He is especially remembered for his work on volcanoes and for writing Volcanoes: What They Are and What They Teach, a book that introduced many readers to geology in an engaging, accessible way. His career also included major honors: he was elected a Fellow of the Royal Society and served as President of the Geological Society.
Beyond his research, Judd played an important part in shaping geological education in Britain. His reputation rested not only on specialist scholarship, but also on his ability to explain the forces that shape the Earth with clarity and enthusiasm.
