Jon Lien

Article summary

Ordin Jon Lien (19 March 1939 - 14 April 2010), nicknamed “the Whale Man”, was a Canadian conservationist, researcher, professor, and organic farmer who founded Memorial University of Newfoundland’s Whale Research Group. From the late 1970s to the early 2000s, Lien released whales and other cetaceans entrapped in fishing nets along the coast of Newfoundland, and innovated now-widely-used whale rescue techniques. He invented The Lien Pinger, an acoustic alarm which is attached to fishing nets to reduce whale entrapments.
