Navajo Code Talker Chester Nez is seen at the State Department in Washington, D.C. on June 5, 2002.
“The last of 29 Navajo Americans who developed an unbreakable code that helped Allied forces win World War Two died in New Mexico on Wednesday of kidney failure at the age of 93,” Reuters reports. “Chester Nez was the last survivor of an original group of 29 Navajos recruited by the U.S. Marine Corps to create a code based on their language that the Japanese could not crack.”
