The 3Rs and Humane Experimental Technique: Implementing Change.

In 1959, the Universities Federation for Animal Welfare (UFAW) Scholars Russell & Burch published the Principles of Humane Experimental Technique in which they laid out the principles of the Three Rs. However, the Three Rs owed much to others. It was UFAW and, in particular, UFAW's Founder and Director, Major Charles Hume who identified the problem that needed to be tackled, and who developed the non-confrontational approach that was needed to both formulate the questions that needed answers and to obtain the answers from the research community.
