In 1925, Man Ray introduced her to Eugène Atget's photographs. She became interested in Atget's work, and managed to persuade him to sit for a portrait in 1927. He died shortly thereafter. She acquired the prints and negatives remaining in Eugène Atget’s studio at his death in 1927. While the government acquired much of Atget's archive — Atget had sold 2,621 negatives in 1920, and his friend and executor André Calmettes sold 2,000 more immediately after his death — Abbott was able to buy the remainder in June, 1928, and quickly started work on its promotion. An early tangible result was the 1930 book Atget, photographe de Paris, in which she is described as photo Editor. Due to a lack of funding, Abbott sold a one-half interest in the collection to Julien Levy for $1,000. Abbott's work on Atget's behalf would continue until her sale of the archive to the Museum of Modern Art in 1968. In addition to her book The World of Atget (1964), she provided the photographs for A Vision of Paris (1963), published a portfolio, Twenty Photographs, and wrote essays. Her sustained efforts helped Atget gain international recognition. Abbott's work is mostly known for her monochrome designs of New York City and it's beautiful architecture. She has three notable pictures one would be the ‘Under the El at the Battery’. The other would be "Night View". Lastly "Portrait Of James Joyce". There are works of her work in the United States at the SFMOMA and the J. Paul Getty Museum.
