https://en.wikipedia.org/wiki/Thalidomide_scandal

In the late 1950s and early 1960s, the use of thalidomide in 46 countries by women who were pregnant or who subsequently became pregnant, resulted in the "biggest man‐made medical disaster ever," resulting in more than 10,000 children born with a range of severe deformities, such as phocomelia, as well as thousands of miscarriages.[1][2]

Thalidomide was introduced in 1956 and was aggressively marketed by the German pharmaceutical company Chemie Grünenthal

It was approved for medical use in the United States in 1998.[3] It is on the World Health Organization's List of Essential Medicines.[8] It is available as a generic medication.[4]

Frances Kathleen Oldham Kelsey, CM (July 24, 1914 – August 7, 2015) was a Canadian-American[1] pharmacologist and physician. As a reviewer for the U.S. Food and Drug Administration (FDA), she refused to authorize thalidomide for market because she had concerns about the lack of evidence regarding the drug's safety.[2] Her concerns proved to be justified when it was shown that thalidomide caused serious birth defects. Kelsey's career intersected with the passage of laws strengthening FDA oversight of pharmaceuticals. Kelsey was the second woman to receive the President's Award for Distinguished Federal Civilian Service, awarded to her by John F. Kennedy in 1962.
