He was born on 17 March 1922 to parents Joaquim Florentino Vaz Júnior and Zilda de Oliveira Vaz. In 1940 he went to
Campo dos Afonsos in
Rio de Janeiro and completed his course in 1943. In 1954 he served in the Directorate of Air Routes, in
Rio de Janeiro, when the opposition to the 2nd government of
Getúlio Vargas intensified. The subsequent investigation indicated as the mastermind of the crime the head of the personal security of the then President of the Republic,
Getúlio Vargas,
Gregório Fortunato, nicknamed "The Black Angel". On the day of the crime, August 5, the protection of Carlos Lacerda was supposed to be done by Major Gustavo Borges, but due to the need to make a flight to complete the hours determined for the aviators, Major Vaz replaced him that night, doing his colleague a favor. Rubens Vaz was promoted
post mortem twice: in 1954 and 1965. He was married to Lígia Figueiredo Vaz, with whom he had four children. ==References==
