J. Russell Smith
Joseph Russell Smith (1874-1966) was an America economist, scholar, geographer. In his 1929 book Tree Crops: A Permanent Agriculture, he used an antecedent term for permaculture. The book is a summarization of his extensive experiments with fruits and nuts as crops for human food and animal fodder. Smith saw the world as an inter-related whole and suggested mixed systems of trees and crops underneath. This book inspired many individuals intent on making agriculture more sustainable, such as Toyohiko Kagawa who pioneered forest farming in the 1930s.
