Christian Lehmann

Christian Lehmann has been a general practitioner in France for 36 years. Of French and Anglo-Mauritian descent, he has been one of the team of doctors who acted in 2018 to debunk the claims of homeopaths and its funding by the French social system.

When Didier Raoult started the hydoxychloroquine controversy, Lehmann and his friends on social networks ( emergency physicians, cardiologists, scientists, GPs…) tried to follow every twist and turn as Il Professore took the international media, and politicians, by storm. Was he a modern-day hero, a snake-oil salesman, or worse? As the tide of Raoult’s supporters grew and became more radicalised, these health-professionals tried to explain why “Primum non nocere”, and the respect of usual procedure, was crucial in evaluating medicines. For some time, that critique went unheard. “In a crisis,  there is no time for studies,” said a French politician.

Lehmann writes a daily column on the pandemic in Liberation, and waited until the time was right to tell the full story.
