Károly Möller was an architect and a writer. His father István Möller was an acclaimed architect and university professor who played a prominent role in the preservation and restoration of Hungarian medieval monuments. He had an important part in the early years of the protection of the Hungarian cultural heritage.
Möller studied at the Budapest University of Technology. In 1932 he visited the USA and the technical novelties he observed there were described in his book A mai technika/Technology nowadays (1939). He worked also in his father’s studio and took part in his restorations and church construction works.
He also led the restoration of several churches. A fine example of his works in this area is the expansion of the Catholic church of John of Nepomuk in Dunapataj, built in 1761, using a unique and new method. The church was literally cut through the walls from the roof to the foundation. A set of steel barrels were placed under the shrine and it was pulled apart manually by several workers using hoists and ropes. The eight-meter wide gap was filled with structures (walls, vault, roof, etc.) similar to those already existing.
He designed several apartment blocks, e.g. buildings under the addresses Marko street 1/b and Lánchíd street 15-17, also on the waterfront. Besides designing the Belgrád quay 2, the Lenz brothers also commissioned him the expansion of their house on Régiposta street 6.
He often took part in constructions as a building engineer by planning the acoustics of different spaces, such as the Átrium cinema. He made researches and published in the field of construction materials and structures, and was the editor of the summary of the period’s architecture, Építési Zsebkönyv I-II./Handbook of construction I-II.
In February 1945, Möller and several members of his family fell victim to the atrocities of the advancing Soviet troops.
