Photographer of which no one knew
This woman was not famous during her lifetime - noneher work was not even published. In 2009, real estate agent John Malof bought several boxes from a storage warehouse, where he found about 100,000 negatives and undeveloped films. After they were scanned, he found great pictures taken in the 60's and 70's. These photos belonged to a woman named Vivian Mayer. The next day, John received more than 200 proposals to make a film about her and her life. This woman photographed her whole life, but she did not show her works to anyone. Using about 200 films a year, she showed them in her room, which she turned into a photo lab. Vivian's talent was not known even by her acquaintances, and only after her death the photographer was appreciated.
