William F. Perrin 1938–2022.

The title of Perrin's presentation was, "The problem of porpoise [= dolphin] mortality in the U. S. tropical tuna fishery" (Perrin, [5]). Bill invited Louella the following year to attend the IWC gill net meeting in La Jolla in 1991 (Perrin et al., [15]) where she presented the bycatch data she gathered from gill net fisheries in the Philippines. Besides being the first person to alert the world to the massive kills of dolphins that were happening in the eastern tropical Pacific tuna fishery in the 1960s, decades later Bill created a compilation of the thousands of documents related to the controversy, along with a searchable bibliography (Perrin, [9]). Bill's critical early research on oceanic dolphins brought world attention to the longstanding and growing problem of incidental mortality of cetaceans in fisheries, but it was also transformative given the huge and enduring impact it had on cetacean science.
