Mary M. Crawford practised at a period when medicine itself was being rebuilt on new foundations.
The record lists Mary M. Crawford as American surgeon (1884-1972).
Mary M. Crawford was born at Manhattan in 1884. Her recorded nationality is United States. She trained at Cornell University.
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 United States matters: hospitals, training and research funding are unevenly distributed, and they decide which questions can be asked.
Mary M. Crawford died in 1972, aged 88. What survives is the change in practice, which is how a medical life is actually measured.
