3. John Stith Pemberton
John Stith Pemberton, the creator of Coca-Cola, was not only a pharmacist but also a passionate experimenter. In his pursuit to find a cure for his morphine addiction, Pemberton conducted self-experiments to understand the effects of the substance on his health. His quest led him to develop a tonic that combined coca leaf extract and kola nuts, ultimately resulting in the formulation of Coca-Cola. While his invention became a global phenomenon, Pemberton’s personal struggle with addiction highlights the complex relationship between innovation and the ethical considerations surrounding self-experimentation in the name of health and wellness.
