Part 6/10:
While Dr. John Kellogg held the spotlight, his brother, William Kellogg, remained in the shadows, helping to develop and market Corn Flakes. Tensions between the brothers regarding the direction of their business were evident; John clung to his health-oriented, unprocessed formula, while William saw an opportunity for profit by introducing flavors and marketing strategies. Their creative differences escalated into a bitter legal feud after William decided to launch his own version of Corn Flakes while John refused to pivot from his original vision.
