Baron Arthur Grumiaux (French: [gʁy'mjo]; 21 March 1921 – 16 October 1986) was a Belgian violinist, considered by some to have been "one of the few truly great violin virtuosi of the twentieth century". He has been noted for having a "consistently beautiful tone and flawless intonation".[2] English music critic and broadcaster, Edward Greenfield wrote of him that he was "a master virtuoso who consistently refused to make a show of his technical prowess".
