Dinescu studied at the Faculty of Journalism of the Ștefan Gheorghiu Academy, and was considered a gifted young poet during his youth, with several poetry volumes published.
[2] His book, Moartea citește ziarul ("Death is reading the newspaper") was turned down in 1988 by the Communist regime's censorship apparatus,[2] and was then published in Amsterdam.
On March 17, 1989, he was fired from România Literară literary magazine,[1] as a result of an anti-totalitarian interview against President Nicolae Ceaușescu, which Dinescu had granted to the French newspaper Libération in December 1988.
[4] He got additional support from poet Doina Cornea, literary critics Alexandru Călinescu and Radu Enescu,[6] and, in November 1989, a collective of 18 young academics and writers, who also wrote letters to Popescu.
According to the investigation of Alex Mihai Stoenescu, Caramitru actually said "Mircea, arată că lucrezi" ("Mircea, show that you're working [on something]" – while holding Dinescu's booklet in front of camera), to which Dinescu replied "La un apel" ("[I'm working] on an appeal [to the people]") – which was indicative of their ill-preparedness and preoccupation in quickly drafting a single revolutionary proclamation on the spot.
In May 2005, in collaboration with the journalist Cristian Tudor Popescu, he started a new newspaper called Gândul, with an initial circulation of 100,000 copies, but he sold his shares in July 2006.
