Zoia Ceaușescu ({{IPA|ro|ˈzoja tʃe̯a.uˈʃesku}}; 28 February 1949 – 20 November 2006) was a Romanian mathematician, the daughter of Communist leader Nicolae Ceaușescu and his wife, Elena. She was also known as Tovarășa Zoia (comrade Zoia).
Biography
File:Zoia and Elena Ceaușescu 1978.jpg
Zoia Ceaușescu studied at High School nr. 24 (now {{ill|Jean Monnet High School|ro|Liceul Teoretic „Jean Monnet” din București}}) in Bucharest and graduated in 1966. She then continued her studies at the Faculty of Mathematics, University of Bucharest. She received her Ph.D. in 1977 with thesis On Intertwining Dilations written under the direction of Ciprian Foias.{{MathGenealogy|id=138942}} Ceaușescu worked as a researcher at the Institute of Mathematics of the Romanian Academy in Bucharest starting in 1974. Her field of specialization was functional analysis. Allegedly, her parents were unhappy with their daughter's choice of doing research in mathematics, so the Institute was disbanded in 1975. She moved on to work for Institutul pentru Creație Științifică și Tehnică (INCREST, Institute for Scientific and Technical Creativity), where she eventually started and headed a new department of mathematics. In 1976, Ceaușescu received the Simion Stoilow Prize{{Cite book|title=Recognizing excellence in the mathematical sciences: an international compilation of awards, prizes, and recipients|date=1997|publisher=JAI Press|editor=Jaguszewski, Janice M.|isbn=0762302356|location=Greenwich, Conn.|oclc=37513025}} for her outstanding contributions to the mathematical sciences.
She was married in 1980 to Mircea Oprean, an engineer and professor at the Polytechnic University of Bucharest.
During the Romanian Revolution, on 24 December 1989, she was arrested for "undermining the Romanian economy", and released eight months later, on 18 August 1990.{{in lang|ro}} Oana Dobre, [http://www.evz.ro/articole/detalii-articol/420087/Invinsa-de-cancer/ "Invinsǎ de cancer"] {{webarchive |url=https://web.archive.org/web/20090520181515/http://www.evz.ro/articole/detalii-articol/420087/Invinsa-de-cancer/ |date=20 May 2009 }}, Evenimentul Zilei, 22 November 2006 After she was freed, she tried unsuccessfully to return to her former job at INCREST, then gave up and retired.{{in lang|ro}} Camelia Onciu, [http://www.monitorulsb.ro/cms/site/m_sb/news/sub_povara_numelui_4967.html "Sub povara numelui"] {{webarchive |url=https://web.archive.org/web/20070929171648/http://www.monitorulsb.ro/cms/site/m_sb/news/sub_povara_numelui_4967.html |date=29 September 2007 }}, Monitorul de Sibiu, 22 November 2006 After the revolution, some newspapers reported that she had lived a wild life, having numerous lovers and often being drunk.[https://www.latimes.com/archives/la-xpm-1990-01-10-mn-364-story.html "Wild Life of Ceaușescu's Daughter Bared"], Los Angeles Times, 10 January 1990, page 2
After her parents were executed, the new government confiscated the house where she and her husband lived (the house was used as proof of allegedly stolen wealth), so she and her husband had to live with friends and relatives. She made efforts to return to INCREST (from where she had been fired), but permission was denied. Zoia sued the institute, but the lawsuit was not completed; in the end, she decided to stop fighting and retire.
After the revolution that ousted her parents, Zoia reported that during her parents' time in power her mother had asked the Securitate to keep an eye on the Ceaușescu children, perhaps she felt, out of a "sense of love".The rise and fall of Ceaușescu, a BBC Television Production written and presented by Edward Behr, 1991 The Securitate "could not touch" the children she said, but the information they provided created a lot of problems for the children.The rise and fall of Ceaușescu, a BBC Television Production written and presented by Edward Behr, 1991 She also remarked that power had a "destructive effect" on her father and that he "lost his sense of judgement".The rise and fall of Ceaușescu, a BBC Television Production written and presented by Edward Behr, 1991
Zoia Ceaușescu believed that her parents were not buried in Ghencea Cemetery; she attempted to have their remains exhumed, but a military court refused her request.{{citation needed|date=April 2020}} The bodies were exhumed for identification and confirmed to be of her parents in 2010, after her death.{{cite web |title=Exhumed Romania body is Nicolae Ceausescu, tests show |work=BBC News |date=3 November 2010 |url=https://www.bbc.com/news/world-europe-11687353 |access-date=12 December 2024}}
Zoia was a chain smoker.{{in lang|ro}} [http://www.evz.ro/detalii/stiri/invinsa-de-cancer-420087.html "o fumătoare înrăită"] ("An inveterate smoker") She died of lung cancer in 2006, at the age of 57, and her remains were cremated at the {{ill|Cenușa Crematorium|ro|Crematoriul Cenușa}}.{{citation|url=https://historia.ro/sectiune/portret/viata-tumultuoasa-a-zoiei-singura-fiica-a-572069.html|title=Viața tumultuoasă a Zoiei, singura fiică a familiei Ceaușescu|lang=ro|first=Alexandru| last=Ionescu|magazine=Historia|access-date=August 16, 2024}}
