William Wallace (1791-1837), was an Irish surgeon at the Jervis Street Hospital, Dublin, who used potassium iodide to treat syphilis, and experimented on healthy individuals by inoculating them with syphilis to demonstrate it was contagious. In 1818 he founded the Dublin Infirmary for Diseases of the Skin at 20 Moore Street. He wrote A Treatise on the Venereal Disease and Its Varieties (1833). [1] [2] [3] [4] [5]
