Wheat flakes, the most common breakfast staple in the United States, was not born by design, but by error. In 1894, W.K. Kellogg was experimenting with a more digestible form of wheat for patients in his brother’s sanitarium. He mixed a wheat paste and accidentally let it stand overnight. In the morning he took the tempered remains, put them through a roller, and each grain emerged as a wide, thin flake. The flakes were a big hit with the patients -- C.W. Post, a future cereal tycoon, among them. Will Keith Kellogg was born on April 7, 1860, in Battle Creek, Mich. "I was my father's seventh son, born on the seventh day of the week, on the seventh day of the month. My father was a seventh child and the name 'Kellogg' has seven letters." It is no wonder that W.K. became a numerologist who secured hotel rooms on the seventh floor, or room numbers and license plates ending in seven.
