The work of Akira Yoshizawa, of Japan, a prolific creator of origami designs and a writer of books on origami, inspired a modern renaissance of the craft. He invented the process and techniques of wet-folding and set down the initial set of symbols for the standard Yoshizawa-Randlett system that Robert Harbin and Samuel Randlett later improved upon. His work was promoted through the studies of Gershon Legman as published in the seminal books of Robert Harbin's Paper Magic and more so in Secrets of the Origami Masters which revealed the wide world of paper folding in the mid-1960s.
