Ion Ionescu de la Brad (June 24, 1818 – December 16, 1891), born Ion Isacescu, was a Moldavian, later Romanian revolutionary, agronomist, statistician, scholar and writer.
Born in Roman, he was the son of a Moldavian Orthodox priest.
Ionescu was educated in Iasi, at the Trei Ierarhi school, and then at the Academia Mihaileana, where he studied with Eftimie Murgu.
He pursued his studies at the University of Paris, where he specialized in agrarian economics.
In 1842, he became a professor of agronomy at the Academia Mihaileana in Iasi, collaborated with the nationalists associated with the journal Propasirea (1844), and, with Nicolae Balcescu, became a principal advocate of land reform in the Danubian Principalities.
Following the idea of the British diplomat David Urquhart, in 1844 Ionescu developed and supported the proposal for the building of an artificial waterway across the Ottoman province of Dobruja, located between the Danube and the Black Sea (Port of Constan?a).
His proposal aimed to support the transportation of the increasing cereal production of the Danubian Principalities toward the seaport of Kustendje (today Constan?a in Romania) for the mutual profit of the Romanian grain producers and Ottoman (mainly Ottoman Greeks and Ottoman Armenians) and foreign merchants.
The Danube–Black Sea Canal and its additional waterworks where completed only in 1987.
Following the failure of the short-lived Moldavian movement in 1848, Ionescu joined Balcescu in Bucharest as a participant in the successful revolution in Wallachia.
He served as leader of the radical faction in the commission established to handle land reform.
After the defeat of the Wallachian revolution in September, 1848, Ionescu went into exile.
Returning to Moldavia in 1857, he was extremely active as an administrator, deputy, and professor after the unification of Moldavia and Wallachia (in 1859-1861) in agrarian reform, agricultural education, and economic and statistical research.
Ionescu de la Brad was a prolific scholar and writer on agricultural and economic topics, publishing over 40 books and pamphlets and nearly 400 articles.
