Robert Webster (virologist)
Robert Gordon Webster (b. 1932) is an avian influenza authority who correctly posited that pandemic strains of flu arise from genes in flu virus strains in nonhumans; for example, via a reassortment of genetic segments (antigenic shift) between viruses in humans and nonhumans (especially birds) rather than by mutations (antigenic drift) in annual human flu strains.
