Charles W. Post was an American entrepreneur and inventor, best known for founding the breakfast cereal company Post Consumer Brands. Born on April 2, 1854, he initially struggled with health issues, which led him to explore healthier food options. This journey inspired him to create his own cereal products. In 1895, Post introduced Grape-Nuts, a cereal made from wheat and barley, which became popular for its unique taste and nutritional value. His success in the cereal industry paved the way for other products, including Post Toasties and Honey Bunches of Oats, making him a significant figure in the development of breakfast cereals.
