An unusual portrait of Edward Jenner and a possible link with Napoleon.

INTODUCTION IN JANUARY 1967 there started the campaign organized by W.H.O. to eradicate smallpox totally. This campaign could not have hoped to succeed without a safe, effective vaccine. Although Edward Jenner probably did not "discover" vaccination, he is usually (and properly) given credit for testing the method and bringing it before the public. Inevitably many engraved portraits of Jenner were published in the nineteenth century.1 The most common are based on a portrait by John Raphael Smith; those considered a better likeness are based on a portrait by James Northcote.2 This paper is concerned principally with an engraved portrait of Jenner by Monsaldi which probably has not been reproduced pteviously.3 It is of interest because it is an ingenious and attractive combination of the Smith and Northcote portraits and also because it forms a possible link between Jenner and Napoleon Bonaparte.
