Wikipedia disagrees with that: "The term "brutalism" was originally coined by the Swedish architect Hans Asplund to describe Villa Göth in Uppsala, designed in 1949 by his contemporaries Bengt Edman and Lennart Holm.[citation needed] He originally used the Swedish-language term nybrutalism (new brutalism), which was picked up by a group of visiting English architects, including Michael Ventris. In England, the term was further adopted by architects Alison and Peter Smithson.[3][4] The term gained wide currency when the British architectural historian Reyner Banham used it in the title of his 1966 book, The New Brutalism: Ethic or Aesthetic?, to characterise a somewhat recently established cluster of architectural approaches, particularly in Europe.[4]"
