100,000th Stolperstein added to the Stolpersteine app
The Stolpersteine app has reached a special milestone. Mr Piet Wollaerts of Burgerinitiatief Struikelstenen Antwerpen has added the 100,000th Stolperstein to the app’s database. It is part of a series of four Stolpersteine that were placed last Sunday in Antwerp for the Itzkowic family at Wipstraat 42.
With this entry, the Stolpersteine app now contains more than 100,000 Stolpersteine, spread across 31 countries. The milestone underlines the growth of the app and the importance of local organizations that help make Stolpersteine visible, verified and supplemented in their own city or region.
The four Stolpersteine at Wipstraat 42 commemorate Esther Goldberg-Itzkowic, Achim Itzkowic, Berthold Itzkowic and Arthur Itzkowic. Their names have now also been included in the app, so that their stories remain accessible to residents, visitors, descendants and future generations.
The Stolpersteine placed in streets and pavements are part of the international art and remembrance project by the German artist Gunter Demnig. The brass memorial stones are placed in front of the last freely chosen home or place of residence of victims of National Socialism. In this way, names and life stories return to the places where people once lived.
The Stolpersteine app is an initiative by Frank van Dijk of Stichting 18 September in Eindhoven. The app began in Eindhoven in 2016 and later grew into a platform for the Netherlands and Belgium. From 2024 onwards, with the help of students from Fontys ICT, work began on its internationalization.
In the summer of 2025, version 1 of the current app was released. Development towards version 2 was continued by Kyllian Warmerdam, one of the participating Fontys ICT students. He completed version 2 in the summer of 2025 as his graduation project.
Since then, the app has made significant progress. In addition to growing to more than 100,000 Stolpersteine in 31 countries, many dozens of local organizations are involved in managing and making Stolpersteine visible. The app is available in 30 languages.
The Stolpersteine app is connected to local and national data sources. One example is Netwerk Oorlogsbronnen in the Netherlands. Links with other collections, municipal data sources and GIS systems used by municipalities can also contribute to careful management and better accessibility.
“This milestone shows the strength of collaboration,” says Frank van Dijk. “Behind every Stolperstein there is a human life. A name. A home. A story that must not be lost. Thanks to local organizations, these names and stories remain visible.”
With the addition of the 100,000th Stolperstein, the Stolpersteine app has developed into an important digital remembrance platform. Its central idea remains unchanged: behind every Stolperstein is a human life that must not be forgotten.
