[6] Chateaubriand was born in Umbuzeiro, state of Paraíba, in the Northeast of Brazil, on October 4, 1892, the son of Francisco José Bandeira de Melo and his wife, Maria Carmem Guedes Gondim.

Intelligent, learned, hard-headed and stubborn, he soon earned a reputation as a self-made man, who had no scruples about approaching and lobbying for influential people who might be serviceable to his personal interests; already as a teenager, he had already made friends with the powerful local Lundgren family of industrialists.

[8] Chateaubriand was a media mogul in Brazil between the late 1930s and the early 1960s and the owner of Diários Associados, a conglomerate that counted at its peak more than a hundred newspapers, radio and TV stations, magazines and a telegraphic agency.

On September 25, 1935, Chateaubriand inaugurated Rádio Tupi (pt) in a ceremony attended by the inventor of radio Guglielmo Marconi, who, ten days earlier, had broadcast the first musical program with a 120-voice orchestra performing the Brazilian National Anthem and was conducted by conductor Villa-Lobos.

[11] After becoming a press tycoon, he eventually combined undeniable journalistic feeling with a totally unscrupulous behaviour, using as his main tool for money making the most extensive use of libel and blackmail, directed against magnates and authorities.

:[8] in the promotion of his pet projects – as in his campaign for the building of airports and training of pilots across Brazil – he would resort to any means whatsoever, having even ordered his thugs to shoot a German businessman who refused to be blackmailed by him[12] Later in life, he would refurbish his São Paulo Museum of Art (MASP) with a whole collection of old European masters' works purchased at bargain prices in impoverished post-WW II Europe, by using funds extorted through blackmail from various Brazilian businessmen.

An often polemic and controversial figure, hated and feared, Chateaubriand has also been nicknamed "the Brazilian Citizen Kane"[14][15] and accused of unethical behavior, for allegedly blackmailing companies[16] that did not place ads in his media vehicles, and for insulting entrepreneurs with lies (such as industry owner Count Francesco Matarazzo).

At the end of his life – especially after a stroke in 1960, that left him speechless, using a wheelchair and communicating with others mostly by means of notes typed in a specially adapted typewriter[22] – he had become a clownish shadow of himself, "a blackmailer who acted as an interloper in the power game of the ruling class".
