Charles Beaumont (January 2, 1929 – February 21, 1967) was an American author of speculative fiction, including short stories in the horror and science fiction subgenres. He is remembered as a writer of classic Twilight Zone episodes, such as "The Howling Man", "Static", "Miniature", "Printer's Devil", and "Number Twelve Looks Just Like You", but also penned the screenplays for several films, such as 7 Faces of Dr. Lao, The Intruder, and The Masque of the Red Death.
In 1963, when Beaumont was 34 and overwhelmed by numerous writing commitments, he began to suffer the effects of "a mysterious brain disease" which seemed to age him rapidly. His ability to speak, concentrate, and remember became erratic. While some people attributed all of this to Beaumont's heavy drinking, his friend and colleague John Tomerlin disagreed: "I was working closely with Chuck at the time, and we were good enough friends for me to know that alcohol by itself could not possibly account for the odd mental state that he was in."
On February 21, 1967, Beaumont died in Woodland Hills, California at the age of 38. His son Christopher later said that his father, "looked ninety-five and was, in fact, ninety-five by every calendar except the one on your watch".
