Kahn was born as
Ludwig Robert Kahn in
Nuremberg, the second child of Beatrice (, 1896–1943) and Gustav Kahn (1884–1942), a Jewish businessman. His maternal grandfather was the liberal rabbi . He was educated at a Jewish school in Nuremberg from 1929 to 1933, then from 1933 to 1939 at the (later named after its founding director
Ephraim Carlebach), the Jewish gymnasium in
Leipzig. Kahn's parents moved to Leipzig, which had a large Jewish community, as life in Nuremberg was becoming increasingly unbearable for Jews. However, they were not free from Nazi persecution. In 1938, Kahn's older sister, Susan Freudenthal (, 1920–2016), emigrated to the United States, aided by her uncle, Josef Freudenthal, who was unable to pay for Kahn's emigration. Following the
mass arrests after Kristallnacht in November 1938, Gustav Kahn was imprisoned at
Buchenwald and
Sachsenhausen concentration camps, and released again in February 1939. Kahn's family attempted to escape from Germany, but their plans to emigrate to the United States failed. On May 10, 1939, Kahn was sent to England with a
Kindertransport. He attended Kendra Hall School in
Croydon from 1939 to 1940 and
West Ham Municipal College in 1940. After
World War II began, Kahn's mother was no longer able to support him financially, so he worked in a tannery. He was interned in a camp on the
Isle of Man as an
enemy alien, then sent on to a camp on the
Île aux Noix in Quebec, Canada. He was able to take classes in this camp, and passed the Junior and Senior Matriculations at
McGill University in 1941 and 1942, respectively. Around this time, he changed the order of his names, calling himself "Robert". A
Halifax Jewish couple took him in and gave him the opportunity to pursue university studies. He studied at
Dalhousie University and obtained his BA in 1944 and his MA (in history and philosophy) in 1945, his thesis titled
Goethe and the French Revolution. At Dalhousie, he was awarded the Avery Distinction and the Joseph Howe Poetry Award. From 1945 to 1948, Kahn studied German Literature and Philology at the
University of Toronto, and received a doctoral degree in German Literature in February 1950, with a thesis about dramatist
August von Kotzebue. His advisor was the Swiss-Canadian Germanist
Hermann Boeschenstein. == Academic career and research interests ==
