Franz Alfred (1880-1962) and Georg Frederich (1921-2010) Kantorowicz.

George Kantorowicz was a senior lecturer/consultant in conservative dentistry at the Royal Dental Hospital who provided ground-breaking treatment for cleft palate children at Great Ormond Street Hospital. His father, Alfred, was a Jewish professor, dean at Bonn Dental School and a world-famous advocate of mobile dental surgeries and prevention for children's dental health, until the Nazis put him in a concentration camp. After important interventions, he became director of Istanbul Dental Institute.
