Nina Lagergren: Swedish businesswoman and advocate for Raoul Wallenberg

Biography and family

Lagergren was born in Stockholm and came from a family with international ties and diplomatic connections. In 1943 she married Gunnar Lagergren; the marriage lasted until his death in 2008. The couple had four children. Their eldest daughter, Nane, later married Kofi Annan, adding an additional international dimension to the family’s profile. Nina Lagergren’s personal life was marked by both private family commitments and public campaigns tied to her half-brother’s legacy.

Campaigning for information about Raoul Wallenberg

Raoul Wallenberg disappeared in Budapest in 1945 while carrying out rescue operations for Hungarian Jews during World War II. He is widely believed to have been detained by Soviet authorities and to have died in Soviet custody, though precise circumstances and timing have remained controversial and unresolved. As his half-sister, Lagergren spent much of her life pressing for fuller investigations, supporting archival research and public inquiries, and encouraging governments and historians to pursue leads. Her efforts helped sustain international attention on the case and the wider historical questions it raised.

Public roles and founding of the Raoul Wallenberg Academy

Beyond campaigning, Lagergren worked to preserve and promote the humanitarian values associated with her brother’s work. She was the founder of the Raoul Wallenberg Academy, an organization dedicated to education about human rights, civil courage and the life of Wallenberg. Through lectures, public appearances and media contributions she sought to connect a historical story with contemporary lessons about individual responsibility and moral courage.

Legacy and notable facts

Nina Lagergren’s legacy is twofold: she played a key role in maintaining public awareness of one of the twentieth century’s enduring mysteries, and she supported initiatives intended to translate that awareness into education and commemoration. Her appearance on Sommar i P1 brought her personal recollections and reflections to a broader audience. She died on 5 April 2019 in Djursholm, Danderyd Municipality, aged 98.
