Biography
Sister Ardeth Platte OP was a Dominican nun of the Grand Rapids Dominicans whose six decades of social-justice organizing began in Saginaw, Michigan, where she helped organize against urban poverty and educational inequity, and culminated in her years as one of the most arrested anti-nuclear activists in the United States. She joined Jonah House in Baltimore in 1995 and moved to the Dorothy Day Catholic Worker community in Washington, D.C., in 2018, continuing her work with Carol Gilbert.
On October 6, 2002, with Sister Carol Gilbert and Sister Jackie Hudson, she cut through perimeter fencing and walked onto the launching pad of an N-8 Minuteman III intercontinental ballistic missile silo near New Raymer, Colorado, splashed her own blood on the silo cover in the shape of a cross, and hammered on the silo with household hammers — an act intended as a literal beating of swords into plowshares, in the symbolic tradition of the Plowshares movement co-founded by Philip Berrigan in 1980. The action, called the Sacred Earth and Space Plowshares II, took place three weeks before the Bush administration's congressional vote on Iraq. The three were arrested at the silo and charged with sabotage and depredation of property.
A federal jury in Denver convicted them in April 2003. On July 25, 2003, U.S. District Judge Robert E. Blackburn sentenced Sister Ardeth — then 67 years old — to 41 months in federal prison, the longest sentence given to any of the three. She served at FCI Danbury in Connecticut, where she was housed alongside, and later widely identified as the inspiration for, the character Sister Jane Ingalls in the Netflix series Orange Is the New Black. She was released in November 2005 and continued anti-nuclear organizing until her death in her sleep at the Dorothy Day Catholic Worker House in Washington, D.C., on September 30, 2020.
The Winter 1998–99 Nukewatch Pathfinder names Kathy Shields Boylan, Carol Gilbert, Ardeth Platte, Frank Cordaro and Larry Morlan as the Gods of Metal Plowshares participants who hammered and poured blood on a B-52 at an Air Force weapons display in May 1998. Their Maryland trial began September 22. The report explicitly states that all five were convicted and jailed before sentencing. January 4 was the announced future sentencing date, and a possible year in prison was exposure rather than completed service.

Separate March 4, 2018 brief Nevada detention and same-day release
The April 2018 Ground Zero newsletter, original page 6, individually names Ardeth Platte among twenty-four Pacific Life Community participants arrested at the Nevada National Security Site on March 4, 2018. Felice Cohen-Joppa’s report says the participants crossed the site boundary, were escorted to a nearby pen, briefly held, processed and released. This is a same-day temporary detention and release, not an overnight prison stay, a served-day sentence, or continuous custody beginning that day. No imprisonment counter or new discrete prison episode is added, and other case dates remain unchanged.
Separate documented 1986 Wurtsmith imprisonment
The December 12, 1986 report and its current-prisoner directory individually identify Ardeth Platte as actually imprisoned for repeated peace leafleting at Wurtsmith Air Force Base. The printed nominal term is twenty-eight-week, and the historical place is Fort Worth, Texas. This is a distinct Wurtsmith sentence-service episode, not the later sabotage/property-damage case already stored. No exact initial arrest, sentence-admission or discharge day is supplied. Directory estimates in February or April 1987 are not verified releases, and the nominal term is not converted to an actual completed total. The report says Platte began a prison fast November 28; a fast-start date is not a jail-admission date.

Additional original custody evidence
The Wurtsmith update individually names Ardeth Platte among five people arrested August 6, 1985 for re-entry trespass. It expressly reports that this individual actually served 5 days in jail. This completed 1985 episode is distinct from later Williams International proceedings or the 1986 Wurtsmith imprisonment. The exact later admission, sentence and discharge days are not printed; August 6 is recorded only as arrest, not assumed continuous custody until an unknown end.
The Nuclear Resister No.35, October 24, 1985: PDF page 7.
The Wurtsmith report individually says Ardeth Platte actually served five days in 1984. This predates both the separately recorded August 1985 five days and the 1986 leafleting imprisonment.
The report dates this Wurtsmith sentence to September 24, 1986. October 15 was a surrender order, not verified intake.
The September 30, 2020 statement from the Dominican Sisters of Grand Rapids, reproduced with these obituaries, dates her move to Jonah House to 1995 and to the Dorothy Day Catholic Worker community to 2018. The contemporary accounts consistently place her death at the Dorothy Day house in Washington, D.C., rather than at Jonah House in Baltimore. Her already recorded birth and death dates, custody cases and sentences are unchanged.

William Critchley-Menor’s 2020 remembrance identifies Platte as arrested alongside him at the immigrant-children protest. His linked first-person account dates that Russell Senate Office Building action to July 18, 2019. No release date or measured duration is supplied.
The same obituary compilation explicitly captions Platte’s Y-12 arrest as July 5, 2010. Knox News reports a later federal jury trespass conviction and a four-month sentence; the photograph caption instead describes two months in jail. These duration statements remain unreconciled; no complete custody timeline is supplied, and no actual total or release date is calculated. These are separate episodes from her already recorded Colorado and Wurtsmith cases.

A September 2019 Global Sisters Report retrospective dates the Sacred Earth and Space Plowshares II sentencing to July 2003. It reports 41 months imposed on Ardeth Platte, with the court also ordering $3,080 restitution for the action and three years of probation for each defendant. These are judicial terms, not measured completed custody durations. The article also identifies Danbury as the prison where Platte was confined after the Colorado action. The report’s estimate of fifteen years in some forty jails and prisons is a combined figure for Platte and Gilbert, not an individual imprisonment total.
Art Laffin’s account individually names Ardeth Platte among six people arrested at the Pentagon on April 19, 2019. Police took them to the Pentagon Police Center, processed them and physically released them within two hours, charging violation of a lawful order. Brief police processing is not recorded as jail admission or a full prison day. The July 18 court appearance was scheduled, not a reported trial outcome.
The Nuclear Resister’s April 20, 2014 report names Ardeth Platte among six people arrested at Langley Air Force Base at the end of a Holy Week peace walk. On Good Friday they attempted to deliver a letter challenging drone warfare and blocked the gate with peace banners. The report says Platte and Baggarly received charges of failure to walk on the left side of the street and summonses for a May 27 hearing; that hearing was prospective. No individual jail admission, exact physical release day, later outcome or custody duration is supplied. Contemporary report, April 20, 2014.
The March 10, 2018 participant report individually names Ardeth Platte among twenty-four people arrested after crossing onto the Nevada National Security Site on March 4. It states that they were briefly held in the nearby pen, processed and released. This same-day arrest and release does not establish jail admission, an individual statutory charge or a completed whole day of imprisonment.
Art Laffin’s March 26, 2016 account individually names Ardeth Platte among four people arrested on Good Friday, March 25, while carrying a cross and praying on the Pentagon sidewalk. They were taken to the Pentagon Police processing center and released after several hours, with notices charging failure to comply with a lawful order. A May 19 hearing was prospective. Police processing is not independently a jail admission or a completed day in prison. Contemporary participant report, The Nuclear Resister.
Art Laffin’s participant report individually names Ardeth Platte among seven people arrested at the Pentagon on December 28, 2017, after trying to deliver the nuclear-weapons prohibition treaty and refusing orders to leave a restricted checkpoint. They were taken to the Pentagon Police center, charged with disobeying a lawful order and released. The report does not individually establish jail admission or a precise physical release day; the announced February 1 hearing is not a verdict or imposed sentence.
Contemporary reports of the May 11, 2011 Y-12 trial describe a federal jury trespass conviction arising from the July 5, 2010 action in Oak Ridge, Tennessee. Judge Bruce Guyton presided, and Jeff Theodore and Melissa Milliken acted for the prosecution. Ardeth Platte was among seven defendants immediately taken into custody after declining continued supervised release pending sentencing. A June 3 update reports Ardeth Platte transferred to the Irwin County Detention Center in Georgia on May 28.

The December 2016 report names this activist among sixteen arrested at the Pentagon witness on December 28 for disobeying a lawful order and subsequently released from processing. Cardboard figures of Daniel Berrigan carried at the action were memorial cutouts, not an additional arrestee. The article supplies no measured jail interval. Contemporary report, The Nuclear Resister.
The April 2015 U.S. Mission to the United Nations report names Ardeth Platte among twenty-two people arrested, processed at the Seventeenth Precinct and released by early afternoon. Its introductory April 27 date conflicts with Art Laffin’s participant account and John LaForge’s separate first-person account, both dating the action April 28. Accounts also differ in their descriptions of summons charges. These differences are preserved rather than silently replacing existing case dates or charges; the planned June 24 hearing is not an eventual court outcome.

Physical custody for the Y-12 prosecution
Contemporary reports identify Ardeth Platte among those jailed July 5–6, 2010 and taken back into custody May 11, 2011. She was sentenced to time served and released September 16, 2011. These two periods total 129 days between the recorded dates; the months on supervised release are excluded. Individual May 11 custody report. Sentencing report. Updated chronology.
