Samoilă Mârza was an Austro-Hungarian-born Romanian photographer best known for taking the only photographs of the 1918 Great National Assembly at Alba Iulia that proclaimed the union of Transylvania with Romania. In 1967, the head of the National Museum of the Union bought from Mârza the camera he used to take the pictures at the assembly. Mârza noted he had to sell other pictures due to financial need. He died at the end of 1967 before he could design a new album to commemorate the upcoming 50th anniversary of the union.
