Isabel Letelier

Isabel Letelier died in Santiago on 30 October 2026, aged 94. Her death was announced by her family and confirmed by her son Juan Pablo Letelier. No cause of death has been made public. It came five weeks after the 50th anniversary of her husband's assassination. She lay in state at Parque del Recuerdo, and her funeral was held there on 1 November 2026. Tributes came from Socialist Party leaders, the Socialist senators' caucus, the Salvador Allende Foundation, IPS and the Transnational Institute.

Isabel Margarita Morel Gumucio was born in Santiago, Chile, in 1932 (one Chilean outlet gave 1935, but her family's announcement of her death at 94 and most tributes point to 1932). Her parents were Alfredo Morel Henriquez and Victoria Gumucio Perez. She was raised in Santiago, the city where she would also die more than nine decades later.

She studied to become a teacher at university, completing studies in Spanish (Pedagogia en Castellano) and philosophy. During her student years she also took classes at the School of Fine Arts in Santiago, an interest in art that later shaped her work collecting and exhibiting Chilean arpilleras.

After marrying Orlando Letelier in 1955 she lived in Venezuela and then, from 1960, in Washington, D.C., where he worked for the Inter-American Development Bank. She returned to Washington in 1971 when he became Salvador Allende's ambassador to the United States, and worked there as a Spanish teacher.

The 1973 coup changed her life. Her husband was arrested and held on Dawson Island, and she joined the relatives of the Dawson prisoners in pressing for their release. After he was expelled to Venezuela in late 1974 the family returned to Washington, and she founded the Chilean Committee for Human Rights, whose board included Senator Edward Kennedy. She ran the network that received Chilean refugees, often housing them in her own home.

After Orlando Letelier and Ronni Karpen Moffitt were assassinated on 21 September 1976, IPS hired her to lead its Human Rights Project. She lobbied the State Department and Congress, organised press conferences and solidarity events with musicians such as Inti-Illimani, Quilapayun, Joan Baez and Peter, Paul and Mary, and tracked the FBI inquiry closely. In 1977 she helped launch the Orlando Letelier Mural Brigade with her sons and the artist Rene Castro. She created the Letelier-Moffitt Human Rights Awards, founded the Third World Women's Project in 1981, built the IPS arpillera collection and, around 1985, set up the Working Group for Democracy in Chile. Her human rights work widened to oppose US policy in Central America and apartheid in South Africa. She returned to Chile after the transition to democracy in 1990.

She married Orlando Letelier in 1955 and they had four sons: Cristian, Jose, Francisco and Juan Pablo. Francisco became an artist and muralist, and Juan Pablo served as a deputy and senator in Chile. Friends remembered her house on 36th Street in Washington as a meeting place, aid collection point and social hub, and recalled that she kept her love of life and friendship through years of grief. Her son Juan Pablo described her as a lover of life, of art and of collective work.

A woman of faith who never belonged to a political party, she spoke with Christian Democrats and Communists alike during the struggle against the dictatorship. She was a committed feminist who organised regular meetings, conferences and workshops on women's rights through the 1970s and 1980s and supported Latin American domestic workers' organisations. She repeatedly rejected bitterness, saying that people who had suffered sought justice so that such crimes would not happen again.

The Institute for Policy Studies called her a gentle giant of the global human rights and women's movements. The Letelier-Moffitt Human Rights Awards she established have honoured more than 100 human rights champions over five decades, and the arpillera collection she assembled is still exhibited at universities and at the Letelier-Moffitt memorial. The legal efforts she supported continued to bear fruit: in June 2026 a Chilean judge sentenced three former secret police agents for the murder of Ronni Karpen Moffitt. The Transnational Institute, which her husband had directed, said she left a legacy of courage, determination and solidarity.

In 2024 the Institute for Policy Studies honoured her at its annual Letelier-Moffitt Memorial Program at Sheridan Circle in Washington. She could not travel, so IPS leaders presented her family with a book of written tributes from friends and admirers.

Her testimony on the assassination, the Dawson Island imprisonment and exile is held in the archive of Chile's Museum of Memory and Human Rights, and documents relating to her are catalogued by the National Archive of Chile. She gave interviews to The Guardian in 1979, to the Times News Service in 1982, to the Transnational Institute in 1998 and 2014, and her story is told in Pascale Bonnefoy's book Rodrigo Rojas De Negri. Hijo del exilio (2021).
