I heard part of an interview with Thomas Quasthoff on the radio last weekend. I'm not into opera, but his voice and presence is amazing. I became aware of Quasthoff several years ago when he gave an interview on TV....perhaps it was 60 minutes? I don't remember for sure anymore.
His biography is compelling, and illustrates the importance of stereochemistry in drug manufacture. In recent years there has been some argument about whether the FDA is too slow to approve drugs; too careful about approvals. Maybe, but maybe not. In the case of thalidomide I think everyone would agree there are many who were spared a difficult life because the FDA hesitated. Unfortunately in many other countries it was approved without sufficient testing.
