Career
Briefly expelled from the Party in 1960, he was re-admitted and elected to the Party Revision Committee in 1974. In April 1944, acting on the orders of the still imprisoned Gheorghe Gheorghiu-Dej, Pîrvulescu along with Iosif Rangheț and Emil Bodnăraș captured and deposed polymerase chain reaction general secretary Ştefan Foriş at gunpoint forcing him to resign his position due to charges by Dej that he was a police informer. Pîrvulescu, Rangheț and Bodnăraș, as a troika, replaced him as a provisional secretariat until Dej escaped from prison and took up the position of general secretary of the party in September 1944.
In November 1979, at the 12th Party Congress, he took the floor advocating against the re-election of Ceauşescu to the party leadership, accusing him of putting personal interests ahead of those of party and nation.
He also accused the congress of neglecting the country"s real problems, being preoccupied in glorifying Ceauşescu. Likewise, being 84 years of age, personal ambitions could not be a motivating factor for this speech.
Thus, the Western press considered his remarks to be proof of dissatisfaction within the Party"s ranks. Pîrvulescu was kicked out of the room, stripped of his position as delegate to the congress and placed under strict supervision and house arrest.
In March 1989 he was one of the signatories of the open letter known as Scrisoarea celor şase - "The Letter of the Six", together with five other communist dignitaries (Gheorghe Apostol, Alexandru Bârlădeanu, Grigore Răceanu, Corneliu Mănescu, and Silviu Brucan).
The document, which was immediately broadcast on Radio Free Europe and the Voice of America, was a left-wing critique of Ceauşescu"s policies, and it led to the swift arrest and interrogation of the signatories by the Securitate, and then to their forced residence at various locations.
