William R. Caddy

William Robert Caddy was a United States Marine who posthumously received the nation's highest military decoration, the Medal of Honor, for his conspicuous gallantry during the Battle of Iwo Jima in World War II. Serving as a Private First Class, he sacrificed his life to shield his platoon leader and platoon sergeant from the blast of an enemy hand grenade.

Caddy was born in Quincy, Massachusetts, and eventually enlisted in the United States Marine Corps Reserve. He was deployed to the Pacific Theater, where his unit became heavily engaged in the assault on Iwo Jima. It was during this intense combat that his selfless actions saved his leadership at the cost of his own life, making him the 72nd Marine of World War II to be awarded the Medal of Honor.

In addition to the Medal of Honor, Caddy was posthumously awarded the Purple Heart for his fatal wounds. His legacy is preserved through the naming of the Marine Corps League Detachment #124 in Quincy, Massachusetts, as well as the renaming of Treasure Island Park in Quincy to the P.F.C. William R. Caddy Memorial Park in 1963.
