Adelchi Negri, an assistant pathologist working in the laboratory of Camillo Golgi, observed these inclusions in rabbits and dogs with rabies. These findings were presented in 1903 at a meeting of the Società Medico-Chirurgica of Pavia. The American pathologist Anna Wessels Williams made the same discovery,[4] but because Negri published his results[5] first, the bodies bear his name.
