Henry Jenner (1767-1851) was the nephew of the well-known Edward Jenner (1749-1823), surgeon and discoverer of the vaccine for smallpox. Henry was also a surgeon and appears to have collaborated closely with his uncle, not only working with him, but publishing with him.
In 1968, M. Doreen Fraser, head librarian of the W. K. Kellogg Health Sciences Library acquired a letter written by Henry Jenner to William Mitchell in 1818. This letter was recently unearthed. The content of this letter is primarily concerned with a vaccine that Jenner has prepared for Mitchell to take back to America with him. Mitchell appears to be inflicted with an unnamed condition. In the letter, Jenner also describes the method for innoculation, but suggests it ought to be done under the guidance of a medical gentleman.
