In page William Crawford Williamson:

"

Williamson was born at Scarborough, North Yorkshire. His father, John Williamson, after beginning life as a gardener, became a well-known local naturalist, who, in conjunction with William Bean, first explored the rich fossiliferous beds of the Yorkshire coast. He was for many years first curator of the Scarborough natural history museum (Rotunda Museum). William Smith, the "father of English geology," lived for two years in the Williamsons' house. Young Williamson's maternal grandfather was a lapidary, and from him he learnt the art of cutting stones.[1]
