1839–1924
A Dutch Catholic priest, museum founder, and careful scholar of names, he moved comfortably between church life and cultural history. He is best remembered for a classic study of Dutch baptismal names and for helping preserve religious art and heritage in Haarlem.

by Jacobus Joannes Graaf
Born in Delft on January 25, 1839, Jacobus Joannes Graaf was a Dutch Roman Catholic priest who later became known as an important figure in church culture and heritage. He served in Ouderkerk aan de Amstel and eventually became a founder-conservator of the Episcopal Museum in Haarlem, showing a lasting interest in preserving the history and material culture of Dutch Catholic life.
As a writer, he is best known for Nederlandsche doopnamen: naar oorsprong en gebruik (1915), a study of Dutch baptismal names that reflects both scholarly curiosity and pastoral knowledge. The book explores how names were used and where they came from, making it appealing not only to language lovers and historians, but also to readers interested in family traditions and everyday religious culture.
Graaf died in Overveen on July 3, 1924. His work still offers a window into Dutch naming customs and the wider world of Catholic history in the Netherlands, giving modern readers something both practical and quietly revealing about the past.
