The focus of this study is to analyze Pedro Ernesto Batista`s public life; who was Rio de Janeiro`s major at the first half of the 30`s. Our hypothesis suggests that the combination of written and spoken communications vehicles - through the using of the radio as an agglutinant and powerful instrument of doctrinaire propaganda - it was, in fact, innovating and previous to the tactics used during the denominated "Estado Novo" (The new State).Most of the ideas used in the process of what has been named "trabalhismo" (labourism) was also anticipated by Pedro Ernesto`s sensible speech and leadership action. He improves his image as a kind and popular doctor dedicated to the attendance of the poor population, using the radio and the most extended newspapers to spread this profile.During his politic campaign for the election to the City hall in 1934 and later as while as working as major in this equivalent period, he became one of the firsts examples of charismatic politician, always caring about the urban population life conditions and interests, specially the workers.This kind of leadership and prestige caused, certainly, the prosecutions that he suffered during the bulge of the anticommunism persecution happened in 1935; wich culminated with his arrest in prison and destitution as major.However, being arrested didn`t meant the end of the powerful of his public image; the symbolic consensuses and dissents, plus the powerful of his public memory had defied even though the Vargas dictatorship.
