Forensic scientist Nicholas Petraco, who analyzed ashes in our podcast "The Troubled Cremation of Stevie the Cat," is currently embroiled in a debate about a Jackson Pollock painting. From The New York Times:
On one side stands Francis V. O’Connor, a stately Old World-style connoisseur with a Vandyke beard and curled mustache, who believes erudition and a practiced eye are essential to judging authenticity. Mr. O’Connor, a co-editor of the definitive Pollock catalog and a member of the now-disbanded Pollock-Krasner Foundation authentication committee, said “Red, Black and Silver” does not look like a Pollock.
“I don’t think there’s a Pollock expert in world that would look at that painting and agree it was a Pollock,” Mr. O’Connor said at a symposium this month.
