Reuven Rubin (1893-1974) was a Romanian-born Israeli painter and Israel's first ambassador to Romania.
Rubin Zelicovici (later Reuven Rubin) was born in Galaţi to a poor Romanian Jewish Hasidic family. He was the eighth of 13 children.
In 1912, he left for Ottoman-ruled Palestine to study art at Bezalel Academy of Art and Design in Jerusalem.
Finding himself at odds with the artistic views of the Academy's teachers, he left for Paris, France, in 1913 to pursue his studies at the École Nationale Supérieure des Beaux-Arts.
