The Raymond Fosdick Papers, dated 1926-1955 and 1979-1983, contain correspondence and American flags sent to Raymond Fosdick by Richard E. Byrd. Byrd had a practice of taking flags on his flights and expeditions then gifting them to friends and benefactors upon his return. Some of the correspondence accompanied the flags and some of the correspondence relates to other topics, such as the Fosdick Mountains. Materials created after Fosdick's death were received or collected by his family and also relate to Byrd and his relationship with Fosdick.
