He studied with
Theodor Aman and
Constantin Stăncescu, who was better known as an art critic. According to
Jacques Doucet, a noted art collector, Gropeanu's debut at the
Salon was very successful and the critics praised him as one of the best young Romanian painters. They were especially impressed with his
pastels of children's portraits and oriental scenes. For many years, he provided drawings to
Le Figaro Illustré and later created illustrations for the stories of
Elena Văcărescu. Although he remained in Paris, he participated in exhibitions at home, notably at the "", an artists' association founded by
Nicolae Vermont and
Ștefan Luchian, and two solo exhibitions at the
Romanian Athenaeum in 1909 and 1912. In 1935, he was named a Knight in the
Legion of Honour. Several of his works were purchased by the French government. The existence of numerous
Orientalist works would suggest that he travelled through North Africa and the Middle East at some unknown date. ==References==
