A total of around 400 code talkers served during World War II or the Korean War. They learned and used the code developed by the first 29. The Navajo Times reports that on June 6 2014, 35 of those are still alive.
On June 4, 2014, the last code talker of the original 29, Chester Nez, died at age 93 in Albuquerque NM, of kidney failure. He wrote :"Code Talker: The First and Only Memoir by One of the Original Navajo Code Talkers of WWII." He received the Congressional Gold Medal in 2001.
There is a very good obituary in the New York Times : "Chester Nez, 93, Dies; Navajo Words Washed From Mouth Helped Win War"
