Williams' foundation announced on Twitter and Facebook that he died at the Veterans Affairs medical center bearing his name in Huntington.
As a young Marine corporal, Williams went ahead of his unit during the Battle of Iwo Jima in the Pacific Ocean in February 1945 and eliminated a series of Japanese machine gun positions.
Later that year, at age 22, Williams received the Congressional Medal of Honor, the nation's highest award for military valor, from President Harry Truman at the White House.
"For me, receiving the Medal of Honor was actually the lifesaver because it forced me to talk about the experiences that I had, which was a therapy that I didn't even know I was doing," Williams said during a 2018 Boy Scouts recognition ceremony in Fairmont, according to the Times West Virginian.
