The young George Hatem journeyed to Shanghai in 1933 to practice medicine and see the sights. The deplorable health and social conditions he found there caused his sympathies to veer quickly to the revolutionary efforts of the Chinese Communist party, and before long he joined the underground Party members in conspiratorial meetings and activities. In 1936 he left Shanghai on a secret Province after completing the Long March. For the next 14 years, Hatem served the Communist troops as physician and adviser. He took the name Ma Haide and became the first foreigner admitted into China’s Communist Party. After the Communist victory in 1949, he became the first foreigner granted citizenship in the People’s Republic. Over the next 40 years, his reputation grew as one of the leading public health physicians in the world. Until his death in 1988, he showed absolute allegiance to the Party. Few foreigners have been accepted into Chinese society as readily as he and certainly none have had such intimate access to 20th century China’s most powerful figures.
