Arno Joseph Mayer (19 June 1926–18 December 2023) was a Luxembourg-born U.S. Army soldier who trained at Camp Ritchie with Class 29. He later served at P.O. Box 1142 and, after the war, became a historian of modern Europe and the Holocaust and the Dayton-Stockton Professor of History at Princeton University.

Biography

Arno Joseph Mayer was born on 19 June 1926 in Luxembourg City, in a small, overwhelmingly Catholic country with a tiny, largely assimilated Jewish minority. His father, politically shaped by left-wing Zionist circles from university days in Heidelberg, helped many German Jews find temporary refuge in Luxembourg before they moved on. By the late 1930s insults and hostility rose, especially toward refugee children. Between 1938 and 1940 the family fled Luxembourg five times on invasion scares; in February 1940 they even moved briefly to Brussels before returning so Mayer and his sister Ruth could take school exams.

On 10 May 1940, after a warning from French intelligence contacts, the family left Luxembourg at 1:00 a.m. Border guards at first refused passage; Mayer’s grandfather’s German passport marked with a large “J” drew suspicion until confirmation of German airborne landings nearby, and the Grand Duchess herself arrived at the border and verified the invasion before crossing. Near Verdun, French soldiers detained the grandfather as an enemy alien until an officer recognized the “J” as Juif and granted a laissez-passer; Mayer tore up the passport as they drove on.

A six-month refugee odyssey followed. A Spain route failed after the French armistice—Spain barred men of military age, and the elderly grandfather could not cross the Pyrenees on foot. Via Marseille they reached Oran and then Morocco, were held at Oujda for lacking visas, and eventually reached Rabat and Casablanca. There the grandfather recalled a distant cousin in Mobile, Alabama, who intervened with U.S. Congressman Frank Boykin to expedite visas. From Casablanca they went through Spanish Morocco and Tangier to Lisbon, then sailed on the Serpa Pinto to New York. Mayer and his father arrived in January 1941; the rest of the family followed in February.

They settled in Washington Heights among German-speaking Jewish refugees. Mayer spoke no English at first, briefly attended a Bronx school for foreign students, then transferred himself to George Washington High School, where refugee classmates included Henry Kissinger and Alan Greenspan. He excelled in French and German placement; a teacher, Mrs. Orock, later wrote in support of an OSS candidacy, though he ultimately served at P.O. Box 1142 instead. He graduated from high school in 1943, worked as an office clerk, and took night classes at City College of New York until he was drafted in 1944 while still awaiting the five-year wait for citizenship.

After tank training at Fort Knox, Kentucky, Mayer was naturalized as a United States citizen in Louisville so he could be sent overseas under then-current law. Selected for military intelligence—his languages and an OCS interview likely flagged his dossier—he was sent to Camp Ritchie, where he trained with Class 29 among European refugees (French, German, and Luxembourgish). He was at Ritchie when President Roosevelt died in April 1945. In June 1945 he was assigned to temporary duty at Fort Hunt’s secret installation, P.O. Box 1142. He was not an interrogator. Designated a “morale officer” for high-value German prisoners—scientists and officers, among them Wernher von Braun—he brought newspapers, magazines, and other comforts and engaged them in conversation meant to put them at ease rather than extract information. He later recalled that others at 1142 did the interrogations and document work while he formed close, non-interrogation relationships with his charges. He believed he was mustered out at Fort Dix, New Jersey.

After the war Mayer studied at City College of New York, the Graduate Institute of International Studies, and Yale, writing his dissertation “The Politics of Allied War Aims” under Hajo Holborn. He taught at Wesleyan (1952–53), Brandeis (1954–58), and Harvard (1958–61), then at Princeton University from 1961 as the Dayton-Stockton Professor of History, specializing in modern Europe, diplomatic history, and the Holocaust (including Why Did the Heavens Not Darken?). He died in Princeton, New Jersey, on 18 December 2023, at 97.
