In 1950, Swedish architect Hans Asplund coined the term "New Brutalism." However, it wasn't until the mid-50s that the term became commonly known thanks to British author and architectural critic, Peter Reyner Banham.
Banham referred to the architectural style simply as "brutalism." The term's origins can be traced to French architect, Le Corbusier, who favored working with "béton brut," otherwise in English known as "raw concrete."
