Radu Beligan, born as Radul Beligan, a Romanian academician, actor, educator, professor and theatre director (born on the Galbeni commune on December 14, 1918).
Radu Vasile, (born 10 October 1942, Sibiu), a Romanian politician, historian and poet, former prime minister of Romania.
Radu Negru (probably in the 13th century) (Radu [the] Black) also known as Radu Vodă (Voivode Radu), Radu Negru, or Negru Vodă, was a mythical early ruler of Wallachia.
This is plausible, given that, in 1289, the Kingdom of Hungary forced all nobles (including those in Transylvania) to adhere to the Roman Catholic Church, an act which could have determined the ethnic Romanian potentates to seek new lands.
Legends surrounding Meşterul Manole also mention Radu Negru as the commissioner of the church, and blend his image with that of Neagoe Basarab, who ruled at a much later date than Radu I. Radu, a name derived from the Slavic word for "joy", is a very common name in Romania nowadays.
