Isabelle Collin Dufresne
French-American artist and author (1935–2014)

Isabelle Collin Dufresne, known professionally as Ultra Violet, was a French-American artist, actress, and writer. She initially studied and worked with Surrealist artist Salvador Dalí before relocating to New York, where she became closely associated with Pop artist Andy Warhol and his Factory scene. As a Warhol superstar she appeared in several of his underground films. Beyond her work in film, she was an active participant in the 1960s and 1970s avant-garde art scene, collaborating with other notable artists and later documenting her experiences in memoirs that chronicled life at Warhol's Factory and her interactions with the era’s leading cultural figures.

Why this record matters
The phrase “french-American artist and author (1935–2014)” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Biographical claims are most persuasive when dates, appointments and relationships can be traced to records created close to the events described. The source revision retrieved here is dated Jul 11, 2026.
A concise life account rarely captures disputed attribution, private networks or the changing language used to describe a career. 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.
