József Diescher was a recognized architect in Pest at the time. Although many of his works have since been demolished, he still participated in the construction of around twenty important buildings. But he also made a significant contribution to the development of Budapest with his activities as a contractor. Between 1850 and 1860, he received more than 200 building permits, most of them as a construction manager and contractor. His name is associated with the construction of the headquarters of the Hungarian Academy of Sciences, as well as the management of the construction of the Temporary House of Representatives (today the Italian Institute), the designer of the latter building was Miklós Ybl. For their merits, the king awarded them with the Ferenc József Order.

He was the greatest Hungarian architect of the second half of the 19th century. The construction of the palace started in the spring of 1862. Its implementation was supervised by Antal Szkalnitzky, and Miklós Ybl from the Academy. One of the main significance of the building is that the academic headquarters was the first Neo-Renaissance public building in Hungary, its architecture and spirit decisively influenced the further development of Hungarian architecture. We can thank him, among many others, for Operaház, Szent István-bazilikát and Várkert Bazár. The most prestigious Hungarian architectural award founded in 1953, countless public spaces and educational institutions, including the Faculty of Architecture of Óbuda University, bear his name.
