(RNS) — Sister Ardeth Platte, a Dominican order nun who fought for nuclear disarmament and later served as an inspiration for a character on the popular Netflix show “Orange Is the New Black,” died in her sleep at the Dorothy Day Catholic Worker House in Washington, D.C., on Wednesday (Sept. 30).

Sister Ardeth Platte is shown outside of the Danbury Federal Correctional Institute in Danbury, Connecticut, after being released from the prison on Dec. 22, 2005. Platte was not due to be released until May 31, 2006, but a judge gave her credit for time already served, according to the Federal Bureau of Prisons. Platte, along with Sisters Jackie Hudson and Carol Gilbert, was arrested in October 2002 after they allegedly cut a chain link fence surrounding a Minuteman III missile silo in northern Colorado. The nuns then used baby bottles to dispense their own blood in the shape of a cross on the silo. (AP Photo/Douglas Healey)
Platte was born in Lansing, Michigan, and began her work for the Dominicans as a teacher. In the 1960s and ’70s, she served as principal and director of alternative education at the former St. Joseph’s Educational Center in Saginaw, Michigan. Her work as an educator impressed many in the community, and Platte was urged to run for the Saginaw City Council. She won, serving as councilwoman from 1973-1985.
