From Timelines
This is a timeline of animal testing, attempting to describe the use of non-human animals for scientific research and emergence of policies regulating testing. Most Nobel Prizes in Medicine have involved some form of animal research.[1]

Time period | Development summary |
---|---|
Ancient history | Animals testing is early documented in the history of biomedical research. Aristotle and Erasistratus already perform experiments on living animals. Greek physician Galen also conducts experiments on animals to advance the understanding of anatomy, physiology, pathology, and pharmacology. Arab physician Ibn Zuhr introduces animal testing as an experimental method for testing surgical procedures before applying them to human patients.[2] |
17th century | Debates on the ethics of animal testing are already conducted in the seventeenth century.[2] Throughout the Age of Enlightenment, physiological experiments on animals are carried out for the purpose of scientific progress. However, the moral acceptability of inducing suffering in animals in the name of scientific advancement also becomes an issue raised in opposition of vivisection before the end of the century.[3] |
18th century | The century marks the rise of moral consideration for animals. Scientists like Stephen Hales and Albrecht Von Haller are known to be concerned about the moral justification of experimenting on animals.[3] |
19th century | By the beginning of the century, the topic of discussion is not if animals can feel or not and to what extent, but rather, whether vivisection is justifiable based on the benefit for humans derived from it. While the second half of the nineteenth century marks the beginning of scientifically meaningful and medically relevant animal research, this period also sees opposition to vivisection becoming widespread in England.[3] |
20th century | Before 1900, animal models were mainly used to study the pathophysiology of infections.[4] Drug testing using animals becomes important in the twentieth century.[2] The 1950s marks the beginning of a new concern for animals on the part of scientists and the public.[5] |
21st century | Recently, the practice of using animals for biomedical research has come under severe criticism by animal protection and animal rights groups, with several countries passing laws to make the practice more ‘humane’.[2] However it has been estimated that 100 million vertebrates are experimented on around the world every year,[6] with 10–11 million of them in the European Union.[7] |

Year | Event type | Details | Location |
---|---|---|---|
300 | Scientific development | Writings of ancient civilizations all document the use of animal testing. These civilizations, led by men like Aristotle and Erasistratus, use live animals to test various medical procedures.[8] | |
1242 | Scientific development | Using animals to study blood circulation, Syrian Arab physician Ibn al-Nafis manages to theorize about the human blood circulatory system. His theories are eventually proven hundreds of years later by William Harvey.[8] | |
1596–1650 | Scientific development | French philosopher René Descartes performs vivisections on animals under his belief that animals are ‘machine-like’, interpreted as a belief that animals can not feel pain.[3] | France |
1660 | Animal testing (basic biology) | Anglo-Irish scientist Robert Boyle theorizes that living beings need air to live – something unknown at the time. Using animals, Boyle tests and proves his theories.[8] | United Kingdom |
1700s | Animal testing (basic biology) | Scientists like Stephen Hales and Luigi Galvani use animals to prove their scientific theories. Some of the theories proved during the 1700s include animation caused by electricity, respiration as combustion, and blood pressure theories.[8] | |

A notorious vivisector, Magendie would shock even many of his contemporaries with the live dissections performed by him at public lectures in physiology.[3] | France |
1840s | Animal testing | Animal experimentation becomes routine after the discovery of anesthetic allows for experiments on animals to continue with less guilt due to less pain inducement.[3] | |
1866 | Organization | Philantropist Henry Bergh founds the American Society for the Prevention of Cruelty to Animals (ASPCA), which would press unsuccessfully for laws to abolish experiments involving animals in the 1860s and 1870s.[10] | United States |
