During her lifetime, Maier’s photographs were unknown and unpublished; many of her negatives were never printed. 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. Maier’s photographs were first published on the Internet in July 2008, by Slattery, but the work received little response. In October 2009, Maloof linked his blog to a selection of Maier’s photographs on the image-sharing website Flickr, and the results went viral, with thousands of people expressing interest. Maier’s work subsequently attracted critical acclaim, and since then, Maier’s photographs have been exhibited around the world.
