Daniel Varney Thompson papers, 1848-1979, bulk 1923-1979

Personal and professional subject files include many relating to engineering consulting projects and research interests. Of particular interest are the files on Bernard Berenson consisting of many letters to Thompson dated 1933-1957 and letters from Nicky Mariano, 1959-1966, and Creighton Giilbert, 1968. All of these items appear on microfilm reel 888. Also of note are a file titled Belle da Costa Greene concerning background information and the circumstances surrounding the death of her adopted son. Extensive correspondence, notes, photographs, and research materials (much photocopied) document Thompson's interest in Kermes beetles, the source of crimson dyes in the Middle Ages.
