Constantin Bălăceanu-Stolnici

Constantin Bălăceanu-Stolnici (born July 6, 1923) is a Romanian neurologist.

He was born in Bucharest, the descendant of al old boyar family. He studied at the Ion C. Brătianu High School in Pitești, graduating in 1941. He then enrolled in the Faculty of Medicine of the University of Bucharest, obtaining in 1948 the title of Doctor of Medicine with thesis Considerații asupra complexului cerebro-dentro-olivar, written under the direction of Ion T. Niculescu [ro]. He then practiced medicine at several hospitals in Bucharest, including Colentina (1952–1957), Dr. Cantacuzino (1957–1965), and Gheorghe Marinescu (1965–1970).

Beginning in 1974, Bălăceanu-Stolnici collaborated as an informant of the Securitate secret police of the communist regime. Initially reported by the press, this was confirmed by CNSAS [ro] and by Bălăceanu-Stolnici himself. Operating under the code names "Paul Ionescu" and "Laurențiu", he was a prolific informer, as well as an agent of influence and agent provocateur for the Securitate. In 2007, Cotidianul published informative notes sent by Bălăceanu-Stolnici to the Securitate, which included a sketch of Vlad Georgescu's Munich apartment, drawn after a visit to his place in October 1984; these notes might have helped in the presumed assassination by irradiation of this Radio Free Europe journalist.

After the fall of comunism, he was elected an honorary member of the Romanian Academy in 1992. In 2003, President Ion Iliescu awarded him the Order of the Star of Romania, Knight rank.
