Which researcher is often referred to as the prince of vivisection?

The title "prince of vivisection" is attributed to Claude Bernard due to his significant contributions to experimental medicine and physiology, particularly in the realm of vivisection, which involves conducting live animal experiments to understand bodily functions and disease mechanisms. Bernard's work laid the foundation for many modern medical practices and his emphasis on scientific method in research brought rigorous experimentation into the field, promoting the use of animals to gain insights into human health and disease. This approach has been both influential and controversial in the evolution of medical research, as it has enabled breakthroughs in understanding various biological processes. Other researchers, like Louis Pasteur and Charles Darwin, made substantial contributions to science but did not focus specifically on vivisection in the same way as Bernard. Rudolf Jaenisch, although known for his pioneering work in genetic engineering, does not have the same historical association with vivisection as Bernard.
