William “Bill” Post, the man who created one of the greatest breakfast treats in Pop-Tarts, died last week, his family announced. He was 96-years-old at the time of his passing. Post worked as the plant manager for the Michigan-based Hekman Biscuit Company, which became known later as Keebler Company. Post is credited with inventing Pop-Tarts, but he would always say it was a team effort, according to his obituary.
