Vivian Maier
A Chicago collector, John Maloof, acquired some of Maier’s photos in 2007, while two other Chicago-based collectors, Ron Slattery and Randy Prow, also found some of Maier’s prints and negatives in her boxes and suitcases around the same time. Maloof, who runs the Maloof Collection, now owns around 90% of Maier’s total output, including 100,000 to 150,000 negatives, more than 3,000 vintage prints, hundreds of rolls of film, home movies, audio tape interviews, and ephemera including cameras and paperwork, which he claims represents roughly 90 percent of her known work. [28] Maloof, who owns the majority of Maier’s known photographs, had previously tracked down a first cousin once removed in France and paid him for the rights; however, Deal believes he has found a closer relative in France who may be the estate’s critic Allan Sekula has suggested that the fact that Maier spent much of her early life in France sharpened her visual appreciation of American cities and society.
