    Not mentioned in the above, but interesting to know, is whether Dugald & Cathie Semple were close relatives of Sir David Semple, inventor of the Semple
    nerve tissue culture anti-rabies vaccine, who in 1904 founded the Pasteur Institute at Kasauli, India, now called the Central Research Institute. Sir David Semple was a vivisector, and was thoroughly decried for it by animal advocates of his own era. In hindsight, however, his introduction of the first mass-produced, inexpensive, and usually effective post-exposure anti-rabies vaccine was a landmark in positively transforming the animal/human relationship, by helping to eliminate fear of rabies. Variants of the Semple vaccine became the first widely deployed pre-exposure anti-rabies vaccine, & were instrumental in the eradication of canine rabies from the U.K. in the post-World War I era, after the Natonal Canine Defence League reversed their initial opposition to vaccinate as an adjunct to canine vivisection, and vaccinated more than 20,000 dogs in the 1919-1923 time frame. The Semple vaccine, made through use of live rabies virus injected into the brains of sheep, was rendered obsolete by the introduction decades ago of longer-lasting vaccines made from killed viruses introduced into egg yolks, but remained in production in India until 2000, and was last produced in Indonesia, to my awareness, as recently as 2010. While Dugald and David Semple obviously approached humanitarian goals from starkly different directions, their careers — whether they were related or not — appear to form separate halves of the wholistic approach to animal welfare and animal rights taking shape in our own time.
