|Dr. Kelsey, receiving the President's Award for Distinguished Federal Civilian Service (highest honor given to federal employees)|
Dr. Kelsey was one of the first officials in the United States to notice (via data!) and raise concerns about thalidomide, the now infamous anti-nausea drug that causes terrible birth defects when administered to pregnant women. The drug was already being widely used throughout the Europe, Canada, and the Middle East to treat morning sickness, but Dr. Kelsey refused to approve the drug for widespread use in the US (despite persistent efforts of Big Pharm to push the drug into the US market). Time proved Dr. Oldham Kelsey correct (clinical trials in the US went very poorly), and her persistence, data analysis, and ethics helped to limit the negative effects of the drug on American children.
I like this example because it shows that government safe guards can work and that we need data in order to provide evidence to protect public health. Also, the hero of this story is a woman...with her doctorate...in the 1960s...which makes her efforts all the more impressive.
