This is the most authoritative and extensive source I've ever come across about the history of Bonsai, its discovery and establishment in the west. It is particularly interesting to note that back in the 1800's westerner's descriptions of bonsai in China and Japan already describe the use of 'modern' bonsai substrates, air layering, wires and 'other mechanical means' to bend branches even in China (which most often only associate with clip and grow techniques). By the way, they also appreciated deadwood on deciduous trees and created it using ants! - Really worth reading it.
