Arnold J. Toynbee was born in London on April 14, 1889, the son of Harry V. Toynbee, a social worker, and Sarah Edith Marshall Toynbee, a historian. Showing academic promise at a young age, Toynbee won scholarships to attend Winchester School from 1902 to 1907, and then Balliol College, Oxford, where he studied Classics and graduated in 1911. In the same year, Toynbee pursued his interest in ancient Greek history by studying at the British Archeological School in Athens. In 1912, he became a fellow and tutor at Balliol College, a position he held for three years. Unable to perform military service because of his health, during World War I he worked in the Political Intelligence Department of the War Office and was a member of the British delegation at the Paris Peace Conference in 1919. He also held the Koraes Chair of Byzantine and Modern Greek Studies at London University in 1919.
