In 1982, a few years after a cat co-authored an influential physics paper, another feline, Bruce Le Catt, submitted a response to the Australasian Journal of Philosophy reviewing an earlier article about prosthetic vision. Today, the journal corrected the paper, stating that “Bruce Le Catt was a pseudonym used by the author David Lewis to discuss some work published under his own name,” Retraction Watch reports. (In fact, Bruce Le Catt—not pictured—was Lewis’s much-loved pet.) The correction was requested by a philosopher at Ohio Dominican University in Columbus, who is writing a book about research integrity. The paper by Bruce Le Catt has been cited four times since its publication.
