Jack Radcliffe

Radcliffe is often cited as an enduring iconic representation (if not the most iconic representative) of the bear aesthetic in pornography, gay culture, and at large. He has been described as "the Marilyn Monroe of bear culture," a "poster boy of bear culture," and a "reigning bear icon." In a 2009 list of bear icons, LGBT pop culture website Queerty stated, "In the bear porn industry, Radcliffe is God. It’s easy to see why– if Plato were a bear, this would be his ideal."

Radcliffe was the most featured cover model in the history of Bear Magazine. In his 2001 forward for author and academic scholar Les K. Wright's The Bear Book II: Further Readings in the History and Evolution of a Gay Male Subculture, former editor-in-chief of Drummer Jack Fritscher noted that Radcliffe remained Brush Creek Media's top box office earner and described him as an icon for the company. Wright also described Radcliffe as the first to embody the "bear beauty" aesthetic with his specifically marketed films. Conversely, Radcliffe has also been specifically identified as an example of the "muscle-bear" body type that later emerged in bear culture, contributing to a more muscular standard of beauty, seemingly in conflict with the "normal," "average," or fat ("chub") aesthetic origins of the bear community.

Radcliffe worked as the chief financial officer of a software consulting company during the late 1990s and early 2000s. He currently works as a realtor.

Radcliffe was "discovered" in 1989 by photographer Chris Nelson. Nelson featured Radcliffe (as "Jack Radcliff") in his coffee table book The Bear Cult, which helped establish the iconic imagery associated with the nascent gay "bear" subculture. He debuted in issue #9 of Nelson and Nelson's partner Richard Bulger's foundational publication Bear Magazine and continued to appear in the publication as a model for the magazine's company, Brush Creek Media, after moving to San Francisco in 1989. Nelson worked as the magazine's photographer, while Bulger served as the magazine's publisher.
