Vivian Dorothea Maier (February 1, 1926 – April 21, 2009) was an American amateur street photographer, who was born in New York City but grew up in France. After returning to the United States, she worked for about forty years as a nanny in Chicago, Illinois. During those years, she took about 100,000 photographs, primarily of people and street scenes in Chicago, although she traveled and photographed in other countries.
Her photographs remained unknown and many of her films where mostly undeveloped until they were discovered by a local Chicago historian and collector, John Maloof, in 2007. Following Maier’s death, her work began to receive critical acclaim. Her photographs have been exhibited in the US, England, Germany, Denmark, and Norway, and have appeared in newspapers and magazines in the US, England, Germany, Italy, France and other countries. A book of her photography titled Vivian Maier: Street Photographer was published in 2011.
