Orban, also known as Urban (Hungarian: Orbán; died 1453), was an iron founder and engineer from Brassó, Transylvania, in the Kingdom of Hungary (today Brașov, Romania), who cast large-calibre artillery for the Ottoman siege of Constantinople in 1453.
Orban was Hungarian, according to most modern authors, while some scholars also mention his potential German ancestry. Alternative theories suggest he had Wallachian roots. Laonikos Chalkokondyles used the term Dacian to describe him.
He had initially offered his services to the Byzantines in 1452, one year before the Ottomans attacked the city, but the Byzantine emperor Constantine XI could not afford Orban's high salary nor did the Byzantines possess the materials necessary for constructing such a large siege cannon. Orban then left Constantinople and approached the Ottoman sultan Mehmed II, who was preparing to besiege the city. Claiming that his weapon could blast 'the walls of Babylon itself', Orban was given abundant funds and materials by the sultan. Orban managed to build the giant size gun within three months at Adrianople, from which it was dragged by sixty oxen to Constantinople. In the meantime, Orban also produced other smaller cannons used by the Turkish siege forces.
Bombarding technology similar to Orban's had first been designed for the Hungarian Army and rose in popularity during the early 1400s all over western Europe, transforming siege warfare. Examples of pieces similar to Orban's productions like the Faule Mette, Dulle Griet, Mons Meg and the Pumhart von Steyr are still extant from the period. Orban, along with an entire crew, was probably killed during the siege when one of his cannons exploded, which was not an unusual occurrence during that time.
