"Chevalier" John Taylor (1703-1772) was the first in a long line of British eye surgeons. While there is some evidence that he showed promise as an eye surgeon early in his career, it became evident that his major talent was that of self-promotion. Dubbing himself "Chevalier" and "Ophthalmiater Royal," Taylor became the self-proclaimed personal eye surgeon to King George II, the Pope and number of European royal families. Wikipedia
