French virologist Luc Montagnier, co-discoverer of HIV, dies at 89

Virologist Luc Montagnier, who, together with his colleague Françoise Barré-Sinoussi,  was awarded the Nobel Prize for isolating the human immunodeficiency virus that was later found to cause Aids, and who since caused controversy with unsubstantiated claims, notably over the causes of autism and the origins of Covid-19, has died at his home near Paris at the age of 89.
