The selected items in this folder cover the years 1911-1932. They consist primarily of correspondence from Marion Estelle Edison to her father, Thomas A. Edison, and her stepmother, Mina Miller Edison. Included are letters referring to Edison's financial support of Marion, who lived in Germany from the 1890s until 1925. The letters also discuss the social, political, and economic conditions in Germany and Switzerland during World War I and its aftermath, Marion's acrimonious divorce from Oscar after the war, and her concern about the state of Edison's business affairs during the 1920s. In addition, there are letters relating to Marion's 1927 appendectomy and hospital stay, paid for by her father, and her 1930 trip to Florida, where she spent two days with Thomas and Mina. A letter from 1932 discusses the bitter feelings among the Edison children after the reading of his will.

Additional letters by Marion Edison and Oscar Oeser can be found in the Charles Edison Fund Collection. Some of the letters in the CEF Collection, scanned from the microfilm, are now in the possession of the Thomas Edison National Historical Park. These items are so indicated in the document information frame above each image.
