Outdoorsy, nature-loving Euell Gibbons was the front man for Grape Nuts breakfast cereal.

Although Grape Nuts gave him widespread celebrity, this Texan with a lived-in face had earlier come to the attention of a fair number of Americans with his remarkably titled book Stalking the Wild Asparagus (1962).

Gibbons was a man who had done more jobs that you could count. He served in the Army, worked in a shipyard, hunted and trapped, was a cowboy and farmed. He also worked as a teacher, wrote for magazines and published a couple of additional books.

Having become a spokesman for natural foods in general, he appeared on talk shows until his death in 1975.
