From 1948 until 2002, Beswick and Royal Albert companies made high-quality porcelain figurines of Beatrix Potter characters.  J. W. Beswick, was a pottery manufacturer, founded in 1894 by James Wright Beswick and his sons John and Gilbert in Longton, Stoke-on-Trent. In 1969, the John Beswick Ltd  business was sold to Doulton & Co. Ltd. The factory closed in 2002 and the John Beswick brand was sold in 2004. 
Beatrix Potter was a beloved writer, painter, scientist, sheep farmer, business woman and generous benefactor. Her first little book, Peter Rabbit, she published herself as her story was rejected by several publishers.  She lived in a life sized dollhouse and every object in her home meant something to her.
