Omar Ribeiro Thomaz

Omar Ribeiro Thomaz was born in Rio de Janeiro on 4 May 1965. He grew up between São Paulo and Lisbon in a household shaped by left politics and dictatorship-era persecution. Folha de S.Paulo reported that his parents were communist militants pursued by the military regime, that he experienced Portugal's Carnation Revolution as a child, and that after the family's return to Brazil his mother was arrested by the organs of repression. Those early displacements, later biographers argued, fed a lifelong interest in how ordinary people endure war, exile, and colonial afterlives.

In Barcelona as a young adult he trained in dramatic arts at the Estudio de Formación de Actores Nancy Tuñón (1988) and completed a degree in art history at the University of Barcelona (1989). Theatre, arts, and the city's cultural life gave him, in Folha's phrasing, ways to be free and to express himself before anthropology became his profession.

After Barcelona, Thomaz turned fully to anthropology in Brazil. He completed a doctorate in social anthropology at the University of São Paulo in 1997 under the supervision of Paula Montero. The dissertation examined representations of the Portuguese Third Empire and supplied the core of Ecos do Atlântico Sul: representações sobre o terceiro império português, published by Editora UFRJ with FAPESP support in 2002.

In 2007 he held a Humboldt Foundation postdoctoral fellowship at the Max Planck Institute for Social Anthropology in Halle (Saale), Germany. He later obtained the livre-docência in social anthropology at Unicamp in 2019. Visiting and guest research appointments included the Institute of Social Sciences at the University of Lisbon, the Centre for Social Studies at the University of Coimbra, EHESS in Paris, Freie Universität Berlin, Eduardo Mondlane University in Mozambique, and the University of Massachusetts Boston.

Thomaz was a Cebrap researcher for more than a decade (about 1994 to 2006). He joined the Novos Estudos editorial board in 1996 and served as editor from 1998 to 2001. In 2001 he entered Unicamp's Department of Anthropology as a doctoral-level professor and rose to full professor (professor titular). He taught in the graduate program in social anthropology, the history program's social history of Africa line, and the doctorate in social sciences.

His research fields were the anthropology of war and conflict and the social history of Africa and the Caribbean. Field sites included southern Mozambique, Uganda, and Haiti; teams built largely of his supervisees worked in Angola, Guinea-Bissau, Namibia, South Africa, Haiti, the Dominican Republic, Serbia, Bosnia, and the former German Democratic Republic. Themes ranged from Salazar-era empire and Indian diasporas in Mozambique to nation formation, catastrophe, racism, and antiracism in Haiti and Brazil.

FAPESP's researcher page lists him as principal investigator and host for thematic and visiting projects on memory, difference, disappearances, humanitarianism, and conflict in Mozambique and Guinea-Bissau. His ORCID is 0000-0002-6474-8662.

Public obituaries emphasize friendship, hospitality, and a multi-species household more than a conventional nuclear family tree. Cebrap described his last home in Barão Geraldo, Campinas, as sheltering birds, tortoises, dogs, fruit trees he planted, and a stream of visitors who returned borrowed books, brought magazines or food, or asked for advice without always announcing themselves.

Folha recalled an unmistakable laugh and a taste for controversy, alongside a generosity that blurred the line between scholarship and care for students and colleagues. Specific names of a spouse or children were not made public in the major death notices of October 2026. Places lived across his life included Rio de Janeiro, São Paulo, Lisbon, Barcelona, Campinas, and long research stays in Mozambique, Haiti, and elsewhere.

Thomaz treated violence not only as battlefield explosion but as the long aftermath of colonial domination, racial hierarchy, and interrupted lives. He asked how people rebuild worlds and invent resistance after war. That sensibility, Folha argued, grew from a biography that included dictatorship, exile, and theatre.

He spoke publicly about Haiti's intellectual history, the silencing of Haitian thought since the nineteenth century, Brazilian military presence in Haiti, antiracism after Durban, and contemporary conflicts from Ukraine to Gaza. In classroom debates and media interviews he linked colonial pasts to present catastrophes. On social media he criticized Brazilian far-right politics and defended democracy, life, and Indigenous survival, including sharp posts about Yanomami deaths and cultural institutions under threat.

Students and colleagues credit Thomaz with forming research communities across Lusophone Africa, the Caribbean, and Europe, and with making Unicamp a reference for Haitian academic reception after 2010. The figure of 47 of 48 Haitian undergraduates completing degrees became a frequently cited measure of that program's success.

Ecos do Atlântico Sul remains a landmark Brazilian study of Portuguese imperial imagination. Cebrap's memorial stressed lasting marks left by his erudition, intensity, and capacity to connect a little-known Mozambican novelist to the tactics of the European far right in a single conversation. Public tributes after his death described Brazilian anthropology as less daring without him.

Ecos do Atlântico Sul won the Brazilian ANPOCS prize for best scientific work in the social sciences in the 2003 competition (for the 2002 publication year), as reported by Cebrap and FAPESP coverage of the prize. His Humboldt postdoctoral fellowship at the Max Planck Institute (2007) and repeated invitations to Lisbon, Coimbra, EHESS, Berlin, Maputo, and Boston marked international recognition. FAPESP's Virtual Library lists him as a long-standing Unicamp-based investigator with thematic grants and host roles for foreign visitors.

His principal book is Ecos do Atlântico Sul: representações sobre o terceiro império português (Editora UFRJ/FAPESP, 2002). He published essays and gave interviews on Haiti, Mozambique, race, war, and Brazilian politics. Recorded lectures and debates circulate on YouTube via IFCH Unicamp, Escola da Cidade, NAP Brasil-África, Antropia Coimbra, and independent channels, covering topics from Anténor Firmin and Haitian thought to Barcelona after crisis and Brazilian forces in Haiti.

Major obituaries appeared in Hora Campinas (13 October 2026) and Folha de S.Paulo (Rodrigo Toniol, 13 October 2026). Cebrap published a formal note of sorrow the same day. English Wikipedia listed him under Deaths in October 2026 without a standalone biography page.

Omar Ribeiro Thomaz died in Campinas on the night of 12 October 2026, aged 61. Cebrap said he was taken by a hard and prolonged illness. English Wikipedia's Deaths in October 2026 entry states the cause as cancer and cites the Cebrap note. Friends and students visited him in the Unicamp hospital in his final days.

According to Hora Campinas and Folha, the Campinas wake was held on Tuesday 13 October from 11 a.m. to 3:30 p.m. at Cemitério Flamboyant. A second ceremony took place in São Paulo on Wednesday 14 October from 9 a.m. to 12:30 p.m. at Cemitério São Paulo in Pinheiros, with burial scheduled for 1 p.m. there.
