This series contains the papers of Frank Altschul's parents, Charles and Camilla Altschul. Though his family was American, Charles was born in England and studied Germany, and he retained a strong interest in European politics and history throughout his life. His papers contain research notes, annotated subject files and correspondence on many topics, including European economics, social issues such as health care and birth control, and research on foreign language publications in the United States. Several files hold correspondence and articles written in response to his writings, including his monograph "The American Revolution in Our School Textbooks" and articles on war debt and war guilt after World War I. The series also holds correspondence between Charles Altschul and his cousin, Dr. Paul Hammerschlag of Vienna. The series contains smaller amounts of information on other members of the Altschul family, such a family tree, a marriage scrapbook for Frank Altschul's uncle and aunt, William and Rosita Altschul, Rosita's diary, and an art history notebook kept by Maria Altschul. Information on Camilla is limited to condolences upon her death in 1952.
