Rev. Roy Hawthorne The Rev. Roy Hawthorne is one of the original windtalkers. They were a group of Navajo men who developed a secret code for American World War II fighters. The Japanese were able to break every other code the military developed. The Navajo code was the only one never solved by the Japanese and is considered the key tool in winning that war. The code was declassified in 2001, and the code talkers received Medals of Honor from President Bush. The new film Windtalkers is based on the story of the codemakers. Hawthorne gives talks about the codemaking process to schoolchildren nationwide.
