Haverbeck's history includes founding the 'Collegium Humanum' in 1963, an organization that initially focused on environmental issues but later aligned with far-right ideologies.

Haverbeck stated in 2020 that she had faced ten trials for her views, highlighting her contentious relationship with the legal system.

Born in 1928, Haverbeck spent decades denying the Holocaust, claiming the mass murder of Jews by the Nazis was unproven, and became a role model in far-right circles.

Her husband, an SS member, influenced her shift towards far-right views, leading her to become a prominent figure in the 'World Federation for the Protection of Life,' which opposed immigration on ecological grounds.

She faced multiple convictions for incitement to hatred, including a prison sentence from 2018 to 2020, and was most recently sentenced to one year and four months in Hamburg.

During her trials, Haverbeck often utilized the court proceedings to promote her propaganda, accompanied by numerous supporters.

Despite overwhelming historical evidence confirming the atrocities committed at Auschwitz, where at least 1.1 million people were murdered, Haverbeck falsely claimed it was not an extermination camp.

Her burial is anticipated to attract significant participation from the far-right scene, with security agencies expecting a large turnout of extremists.

She was well-known in far-right circles and had previously run as a leading candidate for the party 'Die Rechte' in the 2019 European Parliament elections.

Ursula Haverbeck, a notorious Holocaust denier, passed away at the age of 96 on November 20, 2024, as confirmed by her lawyer, Wolfram Nahrath.

Her death prompted condolences from various far-right groups, reflecting her status within the extremist community as a figure of resistance against established historical narratives.

Haverbeck gained notoriety for her repeated denial of the Holocaust and was a leading figure in the extremist scene, celebrated by supporters who dubbed her 'Germany's bravest dissident.'
