Lisa Martino-Taylor is a sociologist whose life’s work has been to uncover details of the Army’s ultra-secret military experiments carried out in St. Louis and other cities during the 1950’s and 60’s. Army archive pictures show how the tests were done in Corpus Christi, Texas in the 1960’s. In Texas, planes were used to drop the chemical. But in St. Louis, the Army placed chemical sprayers on buildings and station wagons. Documents confirmed that city officials were kept in the dark about the tests. The Cold War cover story was that the Army was testing smoke screens to protect cities from a Russian attack. The truth, according to Martino-Taylor was much more sinister.
