Tree shaping has been practiced for at least several hundred years, as demonstrated by the living root bridges built and maintained by the Khasi people of India. Early 20th century practitioners and artisans included banker John Krubsack, Axel Erlandson with his famous circus trees, and landscape engineer Arthur Wiechula. Contemporary designers include "Pooktre" artists Peter Cook and Becky Northey, "arborsculpture" artist Richard Reames, and furniture designer Dr Chris Cattle, who grows "grownup furniture".
