Historical Review: Emanuel Edward Klein—The Father of British Microbiology and the Case of the Animal Vivisection Controversy of 1875.

The new Appendix A of the European Convention for the Protection of Vertebrate Animals Used for Experimental and Other Scientific Purposes, which gives guidelines for accommodation and care of animals and was approved on June 15, 2006, was the main reason the authors decided to investigate the origins of the regulations of animal experiments. Although one might assume that the regulation had its origin in the United Nations conventions, the truth is that its origins are a hundred years old. The authors present a case of the nineteenth-century vivisection controversy brought about by the publication of the Handbook for the Physiological Laboratory in 1873, in which John Burdon-Sanderson, Emanuel Edward Klein, Michael Foster, and Thomas Lauder Brunton described a series of vivisection experiments they performed on animals for research purposes. It was the first case of vivisection to be examined, processed, and condemned for inhuman behavior toward animals before an official body, leading to enactment of the Cruelty to Animals Act in 1876. The case reveals a specific ethos of science in the second half of the nineteenth century, which was characterized by a deep commitment of scientists to the scientific enterprise and their strong belief that science could solve social problems, combined with an overt insensitivity to the suffering of experimental animals. The central figure in the case was Emanuel Edward Klein, a disciple of the Central European medical tradition (Vienna Medical School) and a direct follower of the experimental school of Brücke, Stricker, Magendie, and Bernard. Because of his undisguised attitudes and opinions on the use of vivisection, Klein became a paradigm of the new scientific identity, strongly influencing the stereotypic image of a scientist, and polarizing the public opinion on vivisection in England in the nineteenth century and for some considerable time afterward.
