Our hearts ache as we announce the passing of John Kinsel Sr., a cherished elder and one of the immortal Navajo Code Talkers. At 107, he leaves behind a legacy of unbreakable bravery forged in the fires of Bougainville, Guam, and Iwo Jima. From 1942 to 1946, as a U.S. Marine, he wielded his sacred language, the uncrackable code, to weave the vital communications that defied the enemy and tipped the scales of World War II.
