INTERNATIONAL: French virologist Luc Montagnier, who won a Nobel Prize for his part in discovering the human immunodeficiency virus (HIV) that causes AIDS, has died, on Thursday, February 10.

The 89-year old Montagnier has shared half of the 2008 Nobel Prize for Medicine with fellow French scientist Francoise Barre-Sinoussi for their role in discovering the virus. The other half was awarded to German cancer researcher Harald zur Hausen.

Montagnier, who has sparked controversy in 2020 by saying that he believed the coronavirus was created in a Chinese lab, was born in 1932 in France and has gained a PhD in virology at the University of Paris.

He later became Director of the World Foundation for AIDS Research and Prevention in Paris.

In the years before the onset of the AIDS epidemic, Montagnier had made significant discoveries concerning the nature of viruses and has contributed to understanding of how retroviruses can alter the genetic information of host organisms.

His investigation of interferon, one of the body's defenses against viruses, also opened avenues for medical cures for viral diseases.
