The Julius Grigore Jr. Papers, dated 1992-2004, consist of photocopies of articles Grigore wrote, photocopies of correspondence Grigore sent to Admiral Richard E. Byrd regarding Operation Deep Freeze I, and a monograph Grigore wrote about aerophilately and the First Byrd Antarctic Expedition. Articles written by Grigore from 1967 to 2004 feature topics such as Panama aerophilately (the study of airmail) and the history and research of the wind chill index. The correspondence, which originally dates 1954-1955, contains Grigore’s initial letter of interest and application to join Byrd on Operation Deep Freeze I, and follow-up correspondence by Grigore to inquire about the status of his application. A copy of Grigore’s monograph, “Canal Zone and Panama Aerophilately and Philately Associated with the First Byrd Antarctic Expedition (BAE I), between 1928 and 1930,” is also included in this collection.

The Charles Passel Papers, dated 1937-1953, 1971-2004, and 2012, contains notes, correspondence, photograph slides, and black and white photographs from Passel’s time with the United States Antarctic Service Expedition (1939-1941). Journal articles written by geologists and polar scientists, and a copy of the research paper Passel wrote with Paul Siple, another scientist on United States Antarctic Service Expedition, are also included in this collection. This collection also contains VHS videocassettes recordings of speaking engagements where Passel spoke about his experiences in Antarctica, as well as an oral history interview on audiocassette where he discussed his time on the United States Antarctic Service Expedition. The original VHS videocassettes were created between 1996 and 2004. DVD copies of the VHS videocassettes were created in 2012.
