Sylvester Graham, born in Connecticutt in 1795, invented "Graham crackers" in 1829. He was a vegetarian and an advocate of coarsely ground whole wheat for bread and crackers for its "bulk"--or fiber content as we say today.
He was largely ignored, although whole wheat flour did become known as graham flour. But late in the 19th century, his ideas were expanded upon by Will Keith Kellogg, a Seventh-Day Adventists, who became a physician and was trying to find a way for his patients with digestive problems to consume grain products. He began his cereal company in 1894 in Battle Creek Michigan. He tried boiling grain, but had indifferent results, until he tried the method with corn meal, rolled the results and invented corn flakes.
Charles William Post, who preferred to be known as "C.W." already had a "rest home" in Battle Creek, which may have been what attracted Kellogg. Post touted vegetarianism, and began his breakfast food company in Battle Creek in 1895, some say because Kellogg had started his. The cereal wars were off and running, and Post initially came out on top, because of his canny advertising.
The National Biscuit Company had decided to capitalize on the popularity of crackers, which were then made and sold locally all over the country--people would go into a store, grab a paperbag, and go over the cracker barrel to fill it up. Nabisco sold the "Uneeda Biscuit" which they touted on the basis of its sanitary packaging--and later used electric power generated by the Niagara River, so they put Niagara Falls on their packaging to help sales. They had a host of products . . .
Another big selling point of their waxed paper packaging was that the crackers wouldn't get ruined in damp weather on the way home . . .
Many of their products are familiar to this day . . .
I recall, although i don't know if others will, that animal crackers came with a string on the box, which i thought was a great way to carry them. Apparently, Nabisco intended for them to be hung from the Christmas tree as favors for the children. Animal "biscuits" were baked in England for almost 200 years, but Nabisco trademarked "Animal Crackers" in 1902 . . .
