Seventeenth century England was not without its share of eccentrics, folks who were not the sharpest arrows in the quiver. Roger Crab may certainly be categorized as one of them, although his misfortune at having his skull split open while serving in the Parliamentary Army might provide some excuse for his eccentricity. The unfortunate Crab was sentenced to death after the incident (for having his skull in the wrong place at the wrong time?), but his sentence was later commuted and, upon his release, he became a haberdasher of hats.
His wandering mind somehow happened upon the idea that it was sinful to eat any kind of animal food or to drink anything stronger than water. Determined to pursue a biblical way of life, Crab sold all his hats and other belongings, distributing the proceeds among the poor. He then took up residence in a makeshift hut, where he lived on a diet of bran, leaves and grass (the 16th century equivalent of a kale and edamame diet), and began to produce pamphlets on the wonders of diet.
“Instead of strong drinks and wines,” he wrote, “I give the old man (referring to his body) a cup of water; and instead of roast mutton and rabbit, and other dainty dishes, I give him broth thickened with bran, and pudding made with bran and turnip-leaves chopped together.”
Just as Crab persecuted his own body, others began to persecute him. He was cudgeled and put in the stocks. He was stripped and whipped. Four times he was arrested on suspicion of being a wizard. He bounced from prison to prison until his death on September 11, 1680. Fortunately, our modern society treats its vegetarian eccentrics much more humanely.
Some scholars believe Crab was the inspiration for Lewis Carroll’s Mad Hatter.
Curb Your Carnal Enthusiasm
Sylvester Graham was ordained as a Presbyterian minister in 1826. The Reverend Graham was not your run of the mill minister. He waged a lifelong crusade against alcohol, lust, and white bread.
His disdain of alcohol was inspired by the temperance movement. 
While he accepted the premise that alcohol had useful medicinal qualities, he felt that social drinking was a social danger that could lead to other social activities — namely lust. An unhealthy diet (Graham was also a vegetarian) led to wanton carnal desire, which led to poor health, which led to disease (with a capital D that rhymes with P which stands for you know what).
As one might guess, Graham, like poor Roger Crab, was ridiculed by the media and the public at large (though never cudgeled). He might have been written off as just another crackpot zealot and soon forgotten had it not been for his campaign against white bread. White bread was a bit of a status symbol at the time. Its paleness and the fact that it was purchased rather than homemade separated sophisticates from those bumpkins who made their own dark bread.
Graham thought the use of chemical additives such as alum and chlorine somehow made white bread less than wholesome. Nutritionists tended to agree with him. The whiter the bread, the sooner you’re dead, became their battle cry. Graham went on to create a healthier flour, a healthier bread and — you’ve been waiting for this — the graham cracker.
Sylvester Graham died on September 11, 1851. He probably would not have approved of s’mores.
How To Make S’mores
You’ll need: Wood, matches, graham crackers, chocolate squares (smaller than the graham cracker and fairly thin), marshmallows, a 
pointy stick.
1. Start a campfire.
2. Break a graham cracker along it’s perforation to create two perfect squares.
3. Place a chocolate square on one of the graham cracker squares.
4. Place a marshmallow on the pointy stick and hold it over the fire until it is a nice golden brown (unless you like your marshmallows almost black).
5. Carefully slip the marshmallow off the pointy stick and onto the chocolate graham cracker stack.
6. Place the other graham cracker on top of the marshmallow and press down until the marshmallow just starts to ooze out. This may require some practice.
7. Cleanse your palette with the alcoholic beverage of your choice.
8. Eat the S’more.
9. Cleanse your palette again.
