Knox County native Walter Campbell graduated from the University of Kentucky in 1902 and the University of Louisville Brandeis School of Law in 1906. He was retained by the Kentucky Experiment Station at UK and worked prosecuting food law violations in Louisville, before being scouted by the federal government to help form and run what would later become the Food and Drug Administration. Walter was a key figure in pivotal events like the sulfanilamide disaster. For more on the early years of the FDA, I recommend the article 'Healthy Public Relations: The FDA's 1930s Legislative Campaign' by Gwen Kay.
