Author of 14 books on Criminal Law, Heleno Fragoso was the vice president of the Federal Council of the OAB (the Brazilian Bar Association), and was the Vice President of the International Commission of Jurists, based in Geneva, Switzerland, and of the International Association of Penal Law (AIDP), in Paris (France). A lifelong militant lawyer, Heleno Fragoso died in May 1985, in Rio de Janeiro, at the age of 59.
