Mercy Sister Elizabeth (Betty) Campbell, 91, died Jan. 18.

Born in Wisconsin, she entered the Sisters of Mercy in 1955 and professed perpetual vows in 1961.

Sister Betty ministered in solidarity with the Latin American community in both Central America and the United States for more than 60 years, denouncing human rights violations, criticizing U.S. foreign policies that undermined democratic movements in Latin America and conducting consciousness-raising workshops about the effects of these policies on the poor.

Sister Betty received a bachelor’s degree in nursing from St. Xavier College (now University) in 1960. She ministered at two Sisters of Mercy-affiliated hospitals, in Chicago and in Davenport, Iowa, before going to Sicuani, Peru, in 1962. During her 11 years there, she met Carmelite priest Father Peter Hinde, with whom she would minister and advocate for 56 years, until his death from COVID-19 in 2020.

Over the course of her ministry, Sister Betty and Hinde helped start Catholic Worker communities named Casa Tabor in Washington, D.C.; San Antonio; and Ciudad Juarez, Chihuahua, Mexico.

She also returned to Central America, working in medical clinics in Costa Rica, Nicaragua and Honduras.

In 1980, Sister Betty responded to St. Óscar Romero’s call for volunteers to assist the people of El Salvador, and established clinics in the basements of two parish churches in San Salvador, the capital. While in El Salvador, Sister Betty met and became friends with Maryknoll Sisters Ita Ford and Maura Clarke, Ursuline Sister Dorothy Kazel and lay missionary Jean Donovan, the four American churchwomen who were raped and murdered by the El Salvador National Guard on Dec. 2, 1980.
