About Ernst Posner

Lived 1892 – 1980 (aged 87). Ernst Posner was a German and American archivist, university teacher and historian.

Ernst Maximilian Posner (9 August 1892 – 18 April 1980) was a Prussian state archivist who fled to the United States during World War II where he served as the history department chairman, dean of the graduate school, and director of the School of Social Science and Public Affairs at American University. Additionally, he was a frequent archival consultant to the United States government.

Early life and education Posner was born on August 9, 1892, in Berlin to a wealthy Prussian Lutheran family of both Jewish and Christian heritage. His father, Dr. Carl Posner, was a famous urologist. His uncle, Max Posner, who died ten years before Ernst was born, was an archivist with the Prussian Privy State Archives. Posner attended the University of Berlin where he studied philosophy, history, and languages. He attributed a class that he took with German historian Otto Hintze on U.S. Constitutional history as providing him with the basic knowledge he would need for American history later in his life.

Having previously served in the military during peace-time, he rejoined Imperial German Army during World War I on both the Eastern and Western fronts. He fought in the battles of Tannenberg and the Masurian Lakes. He was wounded in Poland in November 1914. After receiving treatment, he returned, now as a lieutenant, to the front and fought in both Russia and France. In 1918 he was mustered out of the army. He was awarded both the first and second class of the Iron Cross. After the war Posner returned to the University of Berlin where he received his doctorate in February 1920. Later that year he passed the exams necessary to teach in a gymnasium. Posner had to take leave of his various positions and in 1937 he and his wife, Kathe, decided to emigrate to the United States. Posner traveled to the United States for two months in the spring of 1938. With the help of friends, Eugene Anderson of American University in Washington, Waldo Gifford Leland of the American Council of Learned Societies, Solon J. Buck of the National Archives, Posner began to position himself within the world of archives in America. At the National Archives he delivered the Good Friday 1938 lecture on the topic of German archival administration. However, the National Archives was reticent to offer employment to an alien. the Rockefeller Foundation, and the Oberlander Trust looking for any type of employment. Since he was not successful, he eventually returned to Germany. In November 1938, after Kristallnacht, he was arrested and sent to the Sachsenhausen Concentration Camp. Still needing a visa, the Posners ended up in Sweden for four months where he was able to present a lecture entitled "Archival Administration in the United States." Soon after, the American Consul General in Stockholm provided the Posners with visas. As his wife was still in Berlin they both made their way separately to London and then to New York without any of their belongings. For a period of two years, beginning in 1939, Posner and Buck taught a class entitled "The History and Administration of Archives." Most of the students in the class were staff members of the National Archives. This included five archivists who would one day become presidents of the Society of American Archivists: Philip C. Brooks, Oliver W. Holmes, Philip Hamer, Elizabeth Edwards (later Elizabeth Hamer Kegan), and Herbert Angel. When Buck was appointed as the Archivist of the United States in 1941, Posner took control of the influential course. He wrote numerous War Department manuals relating to German and Italian record-keeping practices and served as an advisor for the United States Army's Department Records Branch on German documents. These documents were eventually used as evidence at many crucial war crimes trials.

Posner’s German heritage was questioned by many when he applied for citizenship in 1943. For example, Posner was accused by Senator Kenneth McKellar for attempting to make the bombing of the National Archive easier by switching the records boxes from steel into cardboard. However, on February 16, 1944, Buck appeared before the Senate Subcommittee on Independent Agencies and defended Posner.

Posner also held various positions at American University. They included acting as the chairman of the History Department (1947 - 1961), director of the School of Social Sciences and Public Affairs (1947 - 1961), and dean of the Graduate School (1955 - 1957). One of his responsibilities as Graduate School dean was counseling prospective students. This included Jacqueline Kennedy Onassis when she was considering working towards an M.A. in history.

Posner took great pride in one of the courses that he offered during summers entitled "The Institute on the Preservation and Administration of Archives". According to his own words, "t became the prototype of many such courses now being offered in various parts of the country and has helped to create some esprit de corps and to impart professional know how to those working in the archives field." At that time, Posner's research showed that twelve states did not have any official archivists and that nine of those had no formalized system for the management of permanent government records. In the years following the publication of the book many states began to follow the archival standards proposed by Posner.

One of Posner's most famous books, published in 1972, is entitled Archives in the Ancient World. Posner sought to record the history of archival administration beginning, as few did before him, the ancient world. In the introduction to the work, he argues that "[...] archivists must feel a need to explore the origins of their profession, to understand the circumstances and forces that have determined its evolution, and, with such understanding, to anticipate and-prepare for the future".

For his role in the development of American archival theory and practice, he was sometimes called "the Dean of American archivists."

In 1972, Posner and his wife returned to Europe where they settled in Wiesbaden, Germany.
