In the history of medicine, Niccolò Gualtieri is one of the names that keeps returning.
The record lists Niccolò Gualtieri as Italian physician and conchologist (1688-1744).
Niccolò Gualtieri was born at Florence in 1688.
The circulation of the blood and the microscope arrived within a generation of each other, and medicine acquired a mechanism.
The test of medical work is whether practice changed, not whether the argument was elegant.
Niccolò Gualtieri died in 1744, aged 56. What survives is the change in practice, which is how a medical life is actually measured.
