Stolperstein Dedicated to Christian Daniel Nussbaum.

Introduction

The Stolperstein dedicated to Christian Daniel Nussbaum in Karlsruhe stands as a poignant and personal memorial to the victims of Nazi persecution, offering visitors a unique opportunity to engage directly with the city’s—and Europe’s—difficult history. Stolpersteine, or “stumbling stones,” are small brass plaques set into sidewalks to mark the last freely chosen residences of those targeted by the Nazi regime. Conceived by artist Gunter Demnig in the early 1990s, the Stolpersteine project has become the world’s largest decentralized memorial, with over 107,000 stones installed in nearly 1,900 municipalities across 30 countries (stolpersteine.eu).

Christian Daniel Nussbaum, born in 1888 in Strasbourg, was a Social Democratic Party (SPD) politician and Baden state parliamentarian. His persecution, institutionalization, and suspicious death in the Wiesloch psychiatric institution exemplify the particularly brutal repression of political opponents during the Third Reich (Stolpersteine in Freiburg; Stadtwiki Karlsruhe).

The Stolperstein for Nussbaum, originally installed in 2013 and reinstalled in 2025 after significant controversy, symbolizes societal commitment to confronting complex histories and honoring all victims of totalitarian violence (Wikipedia: Christian Nußbaum). Accessible at any time and free of charge, the memorial invites personal reflection and fosters ongoing public dialogue about the meaning of remembrance.

Historical Background of Christian Daniel Nussbaum

Christian Daniel Nussbaum was born on July 9, 1888, in Strasbourg. An active member of the Social Democratic Party (SPD), he served in the Baden state parliament from 1929 to 1933. Married to Emma Nussbaum (née Eberle), who was Jewish, Nussbaum himself did not identify as Jewish (Stolpersteine in Freiburg). His political activism made him a target during the Nazi seizure of power.

On March 17, 1933, after being threatened with “protective custody” (Schutzhaft) by the police, Nussbaum shot and killed two officers. The Nazis exploited this event to intensify their repression of the workers’ movement in Baden. Declared mentally unfit, Nussbaum was institutionalized and died on June 25, 1939, in the Wiesloch asylum. While official records cite illness as the cause of death, recent research and family accounts suggest he was likely murdered through forced medication, illustrating the Nazis’ abuse of psychiatric institutions for political persecution (Wikipedia: Christian Nußbaum; Stadtwiki Karlsruhe).

The Stolperstein Project: Origins and Significance

Gunter Demnig’s Stolpersteine project, initiated in 1992, aims to restore the names and dignity of individuals persecuted by the Nazis by embedding their memory into the fabric of everyday life (stolpersteine.eu). Each Stolperstein is a 10 x 10 cm brass plaque engraved with the victim’s details and inserted into the pavement at their last chosen residence. The project’s motto, “A human being is forgotten only when his or her name is forgotten,” reflects its deeply personal approach.

The project has grown into a collaborative, participatory memorial involving families, local historians, civic organizations, and municipalities. Its decentralized nature ensures that remembrance is ever-evolving and rooted in the communities most affected.

The Nussbaum Stolperstein: Location and History

The Stolperstein for Christian Daniel Nussbaum was first installed in Karlsruhe on November 10, 2013, at his last freely chosen address. In 2017, city officials removed the stone amid controversy over its inscription, which referenced his killing of police officers. Artist Gunter Demnig and local advocates successfully argued for preserving the original text, and the Stolperstein was reinstated in April 2025 (Wikipedia: Christian Nußbaum; Stadtwiki Karlsruhe). The memorial thus not only commemorates Nussbaum’s life and fate but also embodies the ongoing negotiation of historical memory.
