Manuel Antonio Caballero Agüero (5 December 1931 – 12 December 2010) was a notable Venezuelan historian, journalist, best-selling author and professor of contemporary Venezuelan History at the Central University of Venezuela.
Caballero was born in Barquisimeto, studied history at the Central University of Venezuela and obtained a PhD at University College London. With the publication of his PhD dissertation he became the first Venezuelan author to be published by Cambridge University Press. In 1989 he was invited to teach at Universitá degli Studi di Napoli in Italy. He received the National Award on Journalism (Premio Nacional de Periodismo) and the National History Award (Premio Nacional de Historia, 1994) and in 2005 he was elected as a member of the Academia Nacional de la Historia (or National Academy of History of Venezuela). He wrote regularly for Venezuelan newspapers El Nacional, El Diario de Caracas and most recently El Universal. Despite his past as a left-wing thinker and political activist, in particular against president Rómulo Betancourt, in his latter years he became one of the most vocal and vehement critics of president Hugo Chávez and his administration. He revised his perspective on President Betancourt in a biography written in 2004.
On 2010, he underwent a prostate surgery that triggered a series of infections unresponsive to antibiotics, further complicated by diabetes. He died on 12 December 2010.
