My grandmother's brother-in-law was the head of the research team that developed Rice Krispies and Bran Flakes (but there is no evidence that he had anything to do with the addition of rasins). He did work his way up the Kellogg corporate ladder, but ended up falling from near the top rung. As the story goes, Kellogg went to Europe and left Uncle Gene in charge. W.K. came back early and Gene was golfing instead of working, so he fired him. Eventually Gene's son (my dad's cousin) became one of the founders of Archway cookies.
