Rita Arditti

It eventually caused her death, on 25 December 2009, while she was undergoing a medical procedure in Cambridge.

The Washington Center for Women's Policy presented Arditti with the Jessie Bernard Wise Woman Award in 1994. In 1999, the City of Cambridge conferred its Peace and Justice Award, and the Union Institute & University made her a faculty member emeritus for her 30 years of experience there.

She focused on the activities of the Grandmothers of the Plaza de Mayo. After reading their 1985 book Botín de Guerra (Spoils of War), she was deeply affected by the disappearance of babies carried out by the Argentine government. She met members of the Grandmothers during their visit to Boston, which further aroused her interest. She made several trips to Argentina, where she visited the organization's offices. She poured this knowledge and experience into the book Searching for Life: The Grandmothers of the Plaza de Mayo and the Disappeared Children of Argentina, published by the University of California Press in 1999, with the Grandmothers' approval. It was the first major work in English about the group, and was one document used to support their nomination for the Nobel Peace Prize in 2001.

In the early 1980s, she began a relationship with her life partner, Estelle Disch.

Arditti became interested in investigating the events that occurred in Argentina during the Dirty War, under the military junta that ruled the country from 1976 to 1983. She performed research and engaged in political activism.

She was a longtime activist, co-founding New Words Bookstore in 1974, the Women's Community Cancer Project, and Science for the People. She coedited Test Tube Women: What Future for Motherhood?, a work based on the new technology of reproduction, and Science and Liberation, about politics and science.

When she was attending Barnard College, Arditti met Mario Muchnik, an Argentine who was studying at Columbia, and they began an exchange of correspondence. Later they both returned to Argentina, intending to continue their university studies, but the disorder that prevailed in the country's universities at that time made them relocate to Italy. They started doctorate programs at Sapienza University of Rome – Arditti in biology, and Muchnik in physics. They married, and their son Federico was born in 1960. A year later, Arditti completed her doctorate and got a job in a laboratory in Naples, after which they divorced.
