I recently had the opportunity to interview Frankie Trull, a long time animal welfarist and President of the Foundation for Biomedical Research. The interview appears in the February 2008 edition of Nature Medicine.
Ms. Trull explained to me the difference between animal rights and animal welfare: Animal rights activists tend to think that no animals should be used in scientific experiments; whereas, animal welfare activists tend to think that there is a role for animals in science, but that those animals should be treated humanely and used only when absolutely necessary.
WIRED Magazine also interviewed Frankie Trull in May 2007. Here is a link to that interview: “Frankie Trull”.
