Niall Rudd, It Seems Like Yesterday
(Produced in Aid of the Classical Association Centennial Fund, 2003), p. 21:
Fritz Heichelheim, who had studied under some of the great continental scholars of the 1920s and 30s, had what could only be called a religious devotion to scholarship. Hounded out of Germany in 1937, he had spent a decade in England before emigrating to Canada, by which time he had published two large volumes on Ancient Economic History and over 400 articles. I was never quite sure what his classes made of him. For one thing, he had retained a strong German accent; so in his first lecture on Greek history bewilderment was relieved only when a student passed around a note saying 'Essence' = 'Athens'.
