Edward Jenner

"I am not surprised that men are not thankful to me; but I wonder that they are not grateful to God for the good which he has made me the instrument of conveying to my fellow-creatures."

"A sincere acquiescence in the dispensations of Providence will check discomposure of mind beyond any thing. It will produce a calm in the midst of a storm."

"The highest powers in our nature are our sense of moral excellence, the principle of reason and reflection, benevolence to our creatures and our love of the Divine Being."

"It should not forgotten, however, that it was his "Observations on the natural history of the Cuckoo" (1788) that had won him membership in the Royal Society 10 years before. His work on bird migration, although done at about the same time, was not published until after his death in 1823. Both of these papers were landmarks in ornithological history, for no one prior to Jenner had approached these problems, of brood parasitism and migration, in anywhere near so comprehensive a fashion or with such searching questions."
