"Brigid Polk" was a pseudonym used by Brigid Berlin in the 1960s in some of Andy Warhol's films and on some of her artwork. She reportedly called herself that because she used to "poke" herself so often -- that is, she used to regularly inject amphetamines with a syringe, as she famously did through her jeans in Chelsea Girls (1966).
Completed her education at the Convent of the Sacred Heart Eden Hall in Pennsylvania, a Catholic school where her father had sent her, saying "At least you're not going to get Communism from the nuns!"
Her mother, Honey Berlin, was constantly trying to get her to lose weight as a child, giving her cash for every pound she lost and pharmaceutical "speed" to help her lose it. Brigid was sent to the family doctor at the age of eleven to get amphetamines and Dexedrine (little orange hearts), while her mother took Preludin.
Is portrayed by Coco McPherson in I Shot Andy Warhol (1996) and by Tara Summers in Factory Girl (2006)
She became a permanent employee at the Factory in 1975, working at the front desk and transcribing interviews.
She is the subject of the documentary, Pie in the Sky: The Brigid Berlin Story (2000) - so named because of her obsession with key lime pie and food in general.
She was one of the few superstars who remained a regular friend of Andy Warhol until his death.
Sister of Richie Berlin.
