The people who answered
Sooner or later, a house's history reaches the people who are still living. This project reached descendants of the two founding families, the families of the men whose firm built the corner and worked in it. Some of them answered with works of art, objects, photographs and recollections. Holding something for research and showing it in public are two separate decisions.
Beverley Tyndall, a granddaughter of the painter Gerrit van Duffelen, answered generously for the van Duffelen side, and her answer is now part of the project. She sent family photographs and images of the painter's work. The wall photograph shown here has recorded permission for this publication, under the credit "Collectie familie van Duffelen / Beverley Tyndall". That permission covers this one item: it does not clear the rest of the private collection, nor does it remove rights in the paintings it shows. She holds several of the painter's paintings and etchings and his artist's palette, which was bought separately on the market rather than inherited. brings the fuller set together.
The other founding line answered through Murk Arend Eland, of the Eland-Pelt family. He cleared the family's photographs and objects for publication under the credit "Collectie familie Eland-Pelt (via Murk Arend Eland)". Among them are two chairs the family attributes to the old works, a family group photograph that probably dates from about 1899, and a portrait the family identifies as Cornelis Pelt himself. Clearing a photograph for showing does not by itself license naming the people in it. Anyone still living in a family picture is named only where a public role or a recorded consent covers the name.
The whole page keeps to that rule. It shows and names only what a contributor has cleared, and describes the rest. Permission to show a picture does not give permission to name a living person. Neither is presumed. Each is taken only where it is on record, and what is shown here grows as consent is recorded, never ahead of it.
Two boys laid the commemorative first stone on 3 June 1899: the founders' sons Gerrit van Duffelen, aged nine, and Cornelis Pelt, aged six. It is still in the corner wall. A 2026 owner photograph is registered, but its permission to publish is not, so this page does not show it.
