Margaret Chung practised at a period when medicine itself was being rebuilt on new foundations.
The record lists Margaret Chung as American physician (1889-1959).
Margaret Chung was born at Santa Barbara in 1889. Her recorded nationality is People's Republic of China. She trained at University of Southern California and Keck School of Medicine of USC.
Around the turn of the twentieth century, laboratory medicine, vaccines and public health began to change mortality at population scale.
Clinical knowledge is accumulated slowly and revised often, usually at some cost.
That the work was done from People's Republic of China matters: hospitals, training and research funding are unevenly distributed, and they decide which questions can be asked.
Margaret Chung died in 1959, aged 70. What survives is the change in practice, which is how a medical life is actually measured.
