Paul Janssen

1926–2003 · Belgian · Janssen Pharmaceutica

One of the most productive drug developers of the twentieth century. His fentanyl (1960) remade surgical anaesthesia and, decades later, the illicit opioid supply; haloperidol and risperidone did comparable work in psychiatry. The same lab produced the shorter-acting analogues sufentanil, alfentanil and carfentanil.
