What does vivisectionist mean?
Vivisectionist is a formal noun for a person who performs vivisection, the dissection of living vertebrate animals, or, in a secondary sense, one who advocates that practice. Its clearest use is historical and scientific: critics could identify someone by their role in experiments on live animals, while supporters sometimes described themselves by the same name. The word may also occur in modern debate about animal research, where it can sound neutral in a medical or scientific context but accusatory when used by opponents. The suffix -ist is significant because it identifies a person associated with an activity or position, not merely the activity itself. Vivisectionists are most closely associated with experimental biology and medicine. Because the ethical status and legal regulation of animal experimentation remain contested, the choice of this term can itself signal a speaker's position even when its literal meaning is simply occupational.

"The vivisectionist defended the procedure as necessary to medical research."

"She argued that every vivisectionist had a duty to acknowledge the suffering involved in animal research."
The usual plural refers to multiple people who perform or advocate vivisection.
"Several vivisectionists defended the findings of the experiment."
The name cuts to the bone: a vivisectionist is associated with dissection of living animals, not merely with laboratory experimentation.
