#Albert Ludwig Sigismund #Neisser was a #German #physician, who specialized in #dermatology and venereal diseases. He discovered #gonococcus (1879), the small #bacterium that causes #gonorrhea. In Norway, he examined patients afflicted with leprosy and demonstrated the existence of the bacillus causing the disease (1879). He was the first to make the connection clear between it and the disease. In his studies of syphilis, he failed to find a successful innoculation against the disease, and may even have spread it instead.
