In October 1830, together with his uncle Nicolae Rădulescu, he opened the first privately owned printing press in his country, operating on his property at "Cişmeaua Mavrogheni", in Obor (the land went by the name of "Câmpul lui Eliad"—"Eliad's Field", and housed several other large buildings). Among the first works he published was a collection of poems by Alphonse de Lamartine, translated by Heliade from French, and grouped together with some of his own poems. Later, he translated a textbook on meter and Louis-Benjamin Francoeur's standard manual of "Arithmetics", as well as works by Enlightenment authors—Voltaire's "Mahomet, ou le fanatisme", and stories by Jean-François Marmontel. They were followed, in 1839, by a version of Jean-Jacques Rousseau's "Julie, or the New Heloise".
