He was called upon by the court to serve as an expert on the sleeping drug Contergan. At an early stage Lenz had warned against the use of Contergan and had prompted Contergan-maker Grünenthal to withdraw the drug because he speculated that it could cause deformities in unborn children. The trial against seven high ranking employees of the Stollberg-based Grünenthal company, makers of the drug Contergan, began on 27 May 1968 in the miner's canteen ""Anna"" in Alsdorf near Aachen, Germany. The seven employees were charged with involuntary manslaughter, involuntary assault and the violation of German pharmaceutical laws. - Stolberg/Nordrhein-Westfalen/Germany
