The Kellogg Company, founded in 1906 by Will Keith (W.K.) Kellogg in Battle Creek, Michigan, originated from an accidental 1898 discovery of flaked grains by W.K. and his brother, Dr. John Harvey Kellogg, at the Battle Creek Sanitarium.[1][2][3] W.K. Kellogg launched the Battle Creek Toasted Corn Flake Company, producing the first commercial Kellogg's Corn Flakes, which revolutionized breakfast with ready-to-eat, toasted cereals promoted for health and convenience.[1][5][7] Key achievements include early innovations like Bran Flakes (1915), the first high-fiber cereal, and All-Bran (1916), alongside Rice Krispies (1920s) and global expansions to the UK (1922), Canada (1914), and Australia.[1][2][3][5] The company pioneered nutritional science by hiring the food industry's first dietician, Mary Barber, in 1923, and supported wartime efforts with K-rations in the 1940s.[2][5] Iconic brands followed: Special K (1950s), Frosted Flakes with Tony the Tiger (1952), Froot Loops (1960s), and acquisitions like Pringles (2012, making it the world's second-largest snack company), Keebler, Cheez-It, and Kashi.[2][3][5] Renamed Kellogg Company in 1922 after legal battles with John Harvey over the name, it grew into a dominant force, providing Apollo 11 astronauts' breakfast in 1969 and establishing the W.K. Kellogg Institute for Food and Nutrition Research (1997).[1][3][5] W.K. Kellogg also founded a philanthropic foundation for child welfare.[5] In 2023, the company split into WK Kellogg Co (cereals) and Kellanova (snacks, plant-based), adapting to demands for healthier, organic options amid competition.[2][5] Today, Kellogg's remains a global leader in breakfast cereals and snacks, with commitments like 100% cage-free eggs by 2025, sustaining its legacy of innovation and nutrition.[3]
