His father, future President Nicolae Ceaușescu, was an active member of the Romanian Workers' Party, earning himself various political and military positions; he was the country's Minister of Agriculture at the time Valentin was born.

Unlike many other members of his family, including his younger brother, Nicu, Valentin was not involved in politics.

During that time, his collection of 50 paintings by Romanian masters, engravings by Francisco Goya, in addition to hundreds of rare books, were confiscated.

Working at the Institutul de Fizică Atomică [ro] (IFA) lab in Măgurele, he performed nuclear physics research.
