The C.W. Post Campus of Long Island University is a living memorial to cereal creator Charles William Post. A health food pioneer and marketing genius, C.W. Post built, unaided, the mammoth Post Cereal Company and amassed a $5 million fortune in only five years. On January 1, 1895 in this little white barn in Battle Creek, Michigan, he created a wildly popular caffeine-free coffee substitute called Postum. In 1897, he invented his first cold cereal, Grape-Nuts and in 1899, he created Post Toasties (which later became the rival cereal for the Kellogg's Corn Flakes®, which was introduced to the public in 1906.)
