Johann Jakob Wepfer practised at a period when medicine itself was being rebuilt on new foundations.
The record lists Johann Jakob Wepfer as Swiss pathologist (1620-1695).
Johann Jakob Wepfer was born at Schaffhausen in 1620. His recorded nationality is Switzerland.
The circulation of the blood and the microscope arrived within a generation of each other, and medicine acquired a mechanism.
Clinical knowledge is accumulated slowly and revised often, usually at some cost.
That the work was done from Switzerland matters: hospitals, training and research funding are unevenly distributed, and they decide which questions can be asked.
Johann Jakob Wepfer died in 1695, aged 75. What survives is the change in practice, which is how a medical life is actually measured.
