A largely enigmatic 19th-century writer, Ramón J. Espinosa is known for a provocative 1866 book comparing working-class life in Spain with the lives of enslaved people in Cuba. His work offers a revealing, deeply controversial window into colonial society, labor, and the racial attitudes of its era.

by Ramón J. Espinosa
Little is known about Ramón J. Espinosa’s personal life. In El proletario en España y el negro en Cuba, published in Havana in 1866, he presents himself as an observer who had lived for many years in Madrid before traveling to Cuba, where he studied the island’s social and labor conditions. The book was signed “R. J. E.” and described its author as an independent, eclectic thinker.
The work combines social commentary, narrative sketches, and observations about Spanish workers and enslaved Africans in Cuba. Espinosa argued for gradual rather than revolutionary reform and portrayed slavery in terms that attempted to defend the colonial system, making the book a significant but troubling document of 19th-century Cuban history and pro-slavery ideology. No reliable record of additional major publications or a fuller biography has been confirmed.
