In the late 1950s and early 1960s, the use of thalidomide in 46 countries was prescribed to women who were pregnant or who subsequently became pregnant, and consequently resulted in the "biggest anthropogenic medical disaster ever," with more than 10,000 children born with a range of severe deformities, such as ...
Thalidomide is racemic; while S-thalidomide is the bioactive form of the molecule, the individual enantiomers can racemize to each other due to the acidic hydrogen at the chiral centre, which is the carbon of the glutarimide ring bonded to the phthalimide substituent. The racemization process can occur in vivo.

Widukind Lenz (4 February 1919, Eichenau, Bavaria – 25 February 1995) was a distinguished German pediatrician, medical geneticist and dysmorphologist who was among the first to recognize the thalidomide syndrome in 1961 and alert the world to the dangers of limb and other malformations due to the mother's exposure to this drug during pregnancy.
As director of the Krefeld Children's Hospital, Wiedemann was one of the first to recognise the fatal side effects of thalidomide. While initially considered safe, thalidomide was responsible for teratogenic deformities in children born after their mothers used it during pregnancies, prior to the third trimester. In November 1961, thalidomide ...
