Source-derived 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.

Editorial analysis

Why this record matters

“Jon Lien” is worth following because a concise public description often conceals a longer documentary argument. Here, Lien, American and conservationist provides the most credible route into that argument.

Evidence profile

Critical limits

The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
