In the 1950s and 60s, the U.S. Army sprayed a mystery fog over thousands of Americans who lived in a neighborhood in St. Louis. Mothers shut their windows against it, children ran through it. The Army later admitted the fog contained zinc cadmium sulfide, a chemical that contains cadmium — now a known human carcinogen. But to this day, the Army does not admit harm. Dr. Lisa Martino-Taylor, sociologist and author of Behind the Fog, tells host of “The Truth of the Matter,” Natasha Zouves, why she believes the experiments in St. Louis were part of a larger program spun out of the Manhattan Project — marked by secrecy, deception, and the use of unwitting Americans as test subjects. Why was St. Louis chosen? What else might have been in that spray? And why does this researcher believe the truth remains buried in classified government documents? This is one of the darkest, least-known chapters in American history. And the fight for answers is still unfolding. #StLouis #ColdWarHistory #...
