Héctor Herrera Cajas

On 6 October 1997, Herrera died of a myocardial infarction at Vina del Mar.

On 25 April 1989, Herrera submitted his resignation according to Decree No. 341 provisions.

Herrera was the head of the Universidad Metropolitana de Ciencias de la Educación (UMCE) from 1986 to 1989, and he founded its Classical Studies Center. A few days after his death, the Finis Terrae University opened the celebration of Jornadas de Historia Héctor Herrera Cajas. In 1989, he had been accepted as a full member of Academia Chilena de la Historia and, since November 1997, the main classroom of the PUCV History Institute was named after him.

In 1986, the XVII Byzantine International Congress' Administrative Committee, held in Dumbarton Oaks, accepted his presentation on "The Steppe Peoples and Byzantine Art Formation: From the Tent to Christian Church", but its author could not attend to read it.

In 1986, Herrera was appointed by authorities as the head of the Universidad Metropolitana de Ciencias de la Educación for three years, according to Decree No. 754 on 22 August.

In regards to budgeting, another faculty member questioned one of Herrera's measures when the School of Philosophy was closed, an academic unit that had stopped receiving students since the year when he was appointed as the university's highest authority. In his detractors' opinion, financial reasons given by his rectorate are not convincing considering that he inherited the surplus budget of 1985; that is, $700 million that were used to build two new casinos.

In 1973 at PUCV, Herrera launched Roman Studies Week, which is held every year and has become one of Latin America's most prestigious academic exchanges relative to the history of ancient Rome. Herrera presented works in each of the Roman Studies Week seasons celebrated between 1973 and 1997. In 1976, the PUCV Federation of Students elected him as "the best teacher".

Between 1973 and 1990, Herrera collaborated with Gral. Augusto Pinochet dictatorship's educational policy—through military junta—decided to take on free-market reforms that neither Ibáñez nor Jorge Alessandri wanted to apply, and the initial nationalist line of the 1974 curricular framework was later contradicted by neoliberal economic principles enshrined by the junta in the 1980 Constitution. During the whole regime, there was no major contradiction in the anti-Marxist narrative, which was consensual between classical Western values and the predominance of civic duties over rights (then curtailed). Proof of Herrera's consonance with at least two of the three points (except anti-Marxism) are given by two of his testimonies in a seminar carried out in September 1987 titled "The role of culture in the new institutionality". Politicians from the Second Republic (1925–1973), such as Mario Arnello Romo, attended. There Herrera declared:

Despite Herrera's discomfort in the then-rebellious France, he finished his thesis on the Byzantine Empire's international relations during the Migration Period. The work was published in 1972 in Santiago by the Universidad de Chile Center for Byzantine and Neohellenic Studies, in which Marín says: "It's a study of great intellectual rigor, with an impeccable critical apparatus which all existing sources for the subject are cited and commented; in short, it's a highest level research which has deservedly placed its author among most important Byzantinists of the second half of the 20th century." Herrera's thesis was the only work in the Spanish language which German historian Günther Weiss included in his specialized bibliographic repertoire, which covered everything relevant that occurred in Byzantinistics between 1968 and 1985.

During his term in France, Herrera was a witness of the May 68 unrest and, according to Marín, his epistolary shows how he opposed the so-called "Reform" that was carried out in parallel in Chile. The reform in his country had been promoted by the Christian-Democrat government of Eduardo Frei Montalva, whose party was involved in the 1968 PUCV Rector Elections. Despite his opposition to the reform, according to Alejandro Guzmán Brito in 2013 Roman Studies Week, Herrera supported Vial through his collaboration with Oscar Godoy, with whom he met in Arica.

In 1964, he married Ivonne Lavanchy, who was a member of the Fulbright Commission that was based in Washington D.C., and whose funding had allowed Herrera to dedicate himself to researching Byzantine affairs for seven months in Dumbarton Oaks, which was considered the world's leading center for Byzantine studies, and where he met prominent Byzantinists. A year earlier, accompanied by his family, Herrera had traveled to France on a scholarship obtained after successful negotiations with the Cultural Attaché of the French embassy in Chile: M. Pommier. He obtained his Ph.D. at the University of Bordeaux in 1968 with his thesis "The International Relations of the Byzantine Empire during the time of the great invasions".

Among those influenced by Herrera, Salazar maintained that he preferred him "for his human quality and his way to make lessons". This appreciation did not deny the antagonistic political thought between them, since he was a member of the Revolutionary Left Movement (MIR) while Herrera Cajas was opposed 1960s rebel movements. Similarly, from the start of Augusto Pinochet's dictatorship (1973–1990), Herrera was an ally of the doctrinal line of the Ministry of Education that was aligned with the military regime.

From 1958 to his death, Herrera studied the foreign affairs of the Byzantine Civilization from which he relates topics such as the foundation of its imperial ideology, its relations with the Church, its art and its symbols of imperial power to the Frankish Kingdom and the Abbasid Caliphate.

Among his more important works are Tacitus' Germany: The problem of the meaning of the shield (1957) and "Res Privata–Res publica–Imperium" (1977). The first is considered a pioneering study of the history of mentalities in Chilean historiography. He examines Tacitus' work to analyze the symbolism of the shield to early Germans, then analysed the moves towards medieval history. José Marín said he makes "the source speak in a really remarkable way, since Tacitus himself says little about the subject in question". His article "Res Privata–Res publica–Imperium" "conceptually examines the trajectory of Roman institutions from their foundation until the fall of the Western Empire", and addresses the particularities of the private world and its relationship with public institutions that, at the of the Empire, would perish by socially re-privatizing themselves. Herrera argued that this re-privatization occurred due to the influence of Germanic peoples with their private institutions, and he discarded theories of rupture or continuity between one world and another.

He continued his studies in Germany (1957–1958), where he attended several universities.

Herrera is a follower of Greek historian Fotios Malleros, and is considered the first Byzantinist of Latin America. His works on the history of Byzantium specifically address Byzantine foreign relations and art. At the Universidad de Chile, his alma mater, he taught regular courses. He was the co-founder of the Universidad de Chile Center for Byzantine and Neohellenic Studies, the only institution of its kind on the subcontinent. Later, he was a professor at the Pontifical Catholic University of Valparaíso (PUCV) and since 1954, the Pontifical Catholic University of Chile (PUC).

In 1953, Pontificia Universidad Católica de Valparaíso (PUCV) hired him with the goal of organizing its then-nascent History Institute. In 1960, he became the dean of the PUCV Faculty of Philosophy and Education and the rector of the linked Rubén Castro School.

Although Herrera was not a member of any political party, he supported Ibañismo during the 1950s. In the 1964 presidential elections, he assumed directive functions in nationalist candidate Jorge Prat's campaign in an administration where he was a member of the anticommunist faction of a national-popular government that had two phases: one of a statist policies that received support from the Chilean Socialist Party and was close to Peronism (1953–1955), and another marked by proto–neoliberal economic reforms linked to the Klein-Saks Mission (1955–1958).

After finishing his high-school education, Herrera moved to Santiago, and in 1948 joined the Universidad de Chile. He graduated in 1953 as a history, geography and social sciences teacher. Apart from his regular and compulsory courses, he studied Latin, Greek, German and Sanskrit, and became fluent in English, French and Italian. He was also interested in Chinese, Arabic and Russian, but he did not reach fluency in them. His philology studies were decisive in his intellectual training. In his classes, according to his student and close friend José Marín, the etymology of words was key in his narration of history. During his undergraduate period, Herrera was influenced by teachers like Eugenio Pereira, Mario Góngora, Juan Gómez Millas and Fotios Malleros.

Héctor Enrique Herrera Cajas (13 September 1930 – 6 October 1997) was a Chilean historian and scholar who specialized in Byzantine studies. He is remembered for being a polyglot, and is known for teaching two winners of the National History Prize in his country: Gabriel Salazar and Eduardo Cavieres, researchers in economic and social history.
