Hungarian architect of Austrian descent. He was a key figure of Neoclassical architecture in Hungary. His main work is the Hungarian National Museum (1837-46). In about 1793 he moved to Milan to his half-brother, the architect Leopold Pollack. In 1798 moved to Pest, where in 1808 took a leading role in the city's Beautification Commission, and became increasingly influential. Between 1810 and 1830 he designed many residential buildings, later larger palaces and public buildings. His architectural expression progressed from Baroque towards Neoclassical style. //
