Visiting the Siegfried Ladenburg Stolperstein in Mainz
The Stolperstein dedicated to Siegfried Ladenburg is one of Mainz’s memorial plaques to people persecuted by the Nazi regime. Set into the pavement outside his last self-chosen residence in the Altstadt, it forms part of a citywide network of reminders of Mainz’s Jewish community and its destruction during the Holocaust.
The Stolpersteine (“stumbling stones”) project was created by artist Gunter Demnig in 1992. It is the world’s largest decentralized memorial to victims of Nazi persecution, including Jews, Roma and Sinti, political opponents, LGBTQ+ individuals, and others. Each hand-inscribed brass plaque measures 10x10 cm and is embedded in the pavement in front of a victim’s last self-chosen residence. Its inscription gives the person’s name, birthdate and fate, and, if known, the date and place of death (Germany.info; Mainz.de).
The project’s guiding ethos is expressed in the Talmudic maxim: “A person is only forgotten when his or her name is forgotten.” By bringing names and stories into everyday places, the stones prompt remembrance beyond museums. As of 2025, more than 100,000 Stolpersteine had been installed in over 21 European countries (Germany.info; Mainz.de; Folklife Magazine).
History and memorial significance
Before the Nazi regime, Mainz had a Jewish community of around 2,600 people. Systematic persecution culminated in mass deportations. By 1945, only a few Jewish residents remained, and historians estimate that between 1,300 and 1,400 Mainz Jews were murdered during the Holocaust (Mainz.de).
The first Stolpersteine in Mainz were laid in 2007. As of May 2025, the city and Mainz-Kastel had 351 Stolpersteine and one Stolperschwelle (threshold stone), marking the presence and fate of individual victims (Mainz.de).
Siegfried Ladenburg was a Jewish resident of Mainz who suffered persecution and deportation during the Nazi era. Details about his life may be limited, but his Stolperstein serves as a personal and collective memorial to victims of Nazi terror (findagrave.com).
Stolpersteine installations often involve local residents, descendants, school groups, and sponsoring organizations. Communities, including Mainz, may mark remembrance days by cleaning and polishing the plaques. The stones place remembrance within everyday life and neighborhoods, and have inspired public dialogue, school projects, research, and intergenerational conversation in Mainz (Folklife Magazine; LSB Rheinland-Pfalz).
The project has also prompted debate. Some critics, particularly in cities like Munich, argue that placing names “underfoot” is disrespectful; some municipalities have restricted installations to private property. Supporters say that “stumbling upon” the stones prompts personal reflection and keeps memory alive in the community (Folklife Magazine).
