Professor Gheorghe Mârzescu's contribution to the development of legal education at the University of Iași is essential. A French legal expert, he was actively involved in the institutional and didactic consolidation of the Faculty of Law in its first years of operation. The fact that for a long time he did not have the status of professor shows us the difficult context in which the foundations of the university education from Iasi were laid. Through his works Gheorghe Mârzescu is the founder of the scientific study on civil law at the University of Iași. He was a follower of liberal values and a constant promoter of the principle of laicization, which is why he openly came into conflict with the representatives of the Church. Despite this complexity, the life and work of Professor Gheorghe Mârzescu are less well known today, often being mistaken for his son, an important politician at the beginning of the interwar period. This article aims to bring back to life some of the complex valences of this personality, emphasizing its founding role and the vocation of freedom that he has permanently promoted.
