The collection consists primarily of papers collected by Rogers concerning Albert Schweitzer (1875-1965) as medical missionary and physician at his hospital (founded in 1913) in Lambarene, French Equatorial Africa, after World War II. Included in the collection are 57 letters (1950-1963) by Schweitzer to Rogers; correspondence of Rogers with several of Schweitzer's long-time nurses and associates, such as Emma Haussknecht, Mathilda Kottmann, Emmy Martin, Ali Silver, and Amiya Chakravarty; and selected letters from Winston S. Churchill, Elizabeth Sprague Coolidge, Albert Einstein, Hermann Hagedorn, Eva LeGallienne, Adlai Stevenson, and others concerning the Albert Schweitzer Festival in 1950 and other Schweitzer events. Also present are scrapbooks (1945-1962) containing clippings, tearsheets, photographs, copies of "Cahiers de l'Association Française des Amis d'Albert Schweitzer," articles on his Nobel Prize award in 1954, and his 80th and 85th birthday celebrations, as well as a large amount of audio and visual materials, including approximately 600 color slides of scenes in Lambarene, Alsace, and Germany, tapes of the Boston University radio show "Presenting Albert Schweitzer," interviews with Schweitzer, tapes of natives singing and speaking at Lambarene, a film of "Albert Schweitzer," and phonograph records of Schweitzer playing Bach.

Miriam Rogers was also an artist who created mosaics from natural stones, shells, and semi-precious gems. Her works, numbering over 2000 in 1972 have been shown in several exhibitions. Included in the collection are postcards and brochures illustrating her work.
