C. N. van de (Cornelis Nanning) Poll

Cornelis Nanning van de Poll was a Dutch physician and gynecologist, born in 1860 and died in 1923. Contemporary catalog records for his book Moeder en kind: Zwangerschap bevalling en verzorging van zuigelingen identify him as Dr. C. N. van de Poll, and the work was published in Amsterdam in 1922.

What can be confirmed from available sources paints him as a medical specialist with a public-facing side. Dutch historical material names Cornelis Nanning van de Poll as the gynecology specialist at the Kostelooze Amsterdamsche Polikliniek, a free outpatient clinic in Amsterdam that opened in 1892. His best-known surviving book is a detailed guide to pregnancy, childbirth, and the care of infants, written for readers outside the profession as well as for families preparing for a new child.

A few biographical details appear indirectly in later sources: Dutch and German Wikipedia entries on photographer Willem van de Poll describe Cornelis Nanning van de Poll as Willem's father and a gynecologist. Beyond that, reliable online information about his life is limited, so much of his legacy now seems to rest on his medical writing and his role in Amsterdam's early modern gynecological care.
