Williams (b. 1923), also known as Woody, received the US Military's highest decoration for valor, the Medal of Honor, for heroism during the Battle of Iwo Jima in World War II. He and Charles H. Coolidge are the last two surviving Medal of Honor recipients from World War II. He was awarded the medal by President Truman. He is also a recipient of the Purple Heart.
I mailed to Williams on November 16 and got the card back on November 23, for a 7-day TAT.
