Ödön Lechner (1845-1914) is one of the greatest and most original creators of Hungarian architecture, who also owns a distinguished place among the architectural geniuses of the early 20th century. In 2014 we remembered the 100th anniversary of his death, which was included in UNESCO’s list of international anniversaries. On this occasion, the Museum of Applied Arts and the Institute of of HAS RCH jointly organized an international, English-Hungarian scientific conference and a large-scale exhibition.
