[1] 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.

School did not hold his attention, and his last name exposed him to ridicule, so Charles Nutt found solace as a teenager in science fiction.

He dropped out of high school in tenth grade to join the Army in the final years of World War II.

Beaumont and several friends built their own SCCA H Modified racecar dubbed the "Monzetta", consisting of Panhard mechanicals and a Devin body and chassis, which was raced at many Southern California tracks including Paramount Ranch Racetrack.

[4][5] His cautionary fables include "The Beautiful People" (1952), about a rebellious adolescent girl in a future conformist society in which people are obligated to alter their physical appearance (adapted with friend and frequent writing partner John Tomerlin as an episode of Twilight Zone, "Number 12 Looks Just Like You"), and "Free Dirt" (1955), about a man who gorges on his entire vegetable harvest and dies from having consumed the magical soil he used to grow it.

[6] In the story, a heterosexual man meets his lover in a gay orgy bar; they try to have sex in a curtained booth (she dressed in male drag) and are caught.

Beaumont wrote several scripts for The Twilight Zone, including an adaptation of his own short story, "The Howling Man", about a prisoner who might be the Devil, and the hour-long "Valley of the Shadow", about a cloistered Utopia that refuses to share its startlingly advanced technology with the outside world.

Beaumont scripted the film Queen of Outer Space from an outline by Ben Hecht, deliberately writing the screenplay as a parody.

Beaumont was much admired by his colleagues (Ray Bradbury, Harlan Ellison, Richard Matheson, Robert Bloch, Roger Corman).

Many of his stories have been re-released in the posthumous volumes Best of Beaumont (Bantam, 1982) and The Howling Man (Tom Doherty, 1992), and a set of previously unpublished tales, A Touch of the Creature (Subterranean Press, 1999).

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.

Several fellow writers, including Nolan and friend Jerry Sohl, began ghostwriting for Beaumont during 1963–1964, so that he could meet his many writing obligations.
