About Mario Héber Usher

Lived 1921 – 1980 (aged 58–59). Mario Héber Usher was an Uruguayan politician.

Mario Héber Usher (1921 – 19 May 1980) was a Uruguayan political figure.

Background

Mario Héber was a prominent member of the Uruguayan National (Blanco) Party. His parents were Blanca Usher Conde and Alberto Héber Uriarte (grand-nephew of Juan D. Jackson). He was from a well-known political family; his brother Alberto Héber was President of Uruguay from 1966 to 1967; his son Luis Alberto Héber is a National Party Senator and former Deputy.

Elected offices

In 1958 he was elected a Deputy. Usher was President of the Chamber of Deputies of Uruguay from March 1, 1966, to March 1, 1967. In 1971 he was elected a Senator.

Family incident

In 1978 his wife, Cecilia Fontana, was assassinated by poison intended for himself, sent by an unknown person or group. Other politically prominent families were also - unsuccessfully - targeted. This tragic incident has been widely blamed on political violence associated with the period of civilian-military rule in Uruguay, which began in 1973, after which Mario Héber and many other politicians were proscribed from political activities, but which he continued to pursue clandestinely.

Diplomatic repercussions

In 2008 US Ambassador to Uruguay Frank E. Baxter was involved in a series of controversial high level exchanges in respect of these yet unresolved issues.

Death

He died in 1980.
