Prominence

John Hardcastle was an amateur geologist who made an internationally significant scientific contribution to geology through his discovery of loess stratigraphy. The study of stratigraphic features of loess deposits provides information about past climates and can give an indication about what to expect in the future. He also gave lectures on geology, including one to the Educational Institute in 1905 and one to the Mechanics
Institute in 1910.

His findings are even more remarkable given that John Hardcastle had no formal education in the field, but was self-taught. While John Hardcastle is relatively unknown, his contribution to geology as a pioneer has been recognised in his field. In 1991 scientists from all over the world met in Beijing to discuss the work of John Hardcastle – in particular his discovery of the geological relationship between loess deposits and
climates of past years.
