"Although some important works of art now in the Wallace Collection were acquired in the eighteenth century by the 1st and 2nd Marquesses of Hertford (for example some paintings by Canaletto, Reynolds and Gainsborough), the first member of the family to show a real interest in art was the 3rd Marquess" (www.wallacecollection.org [2])
"It was, however, his son the 4th Marquess, one of the greatest collectors of the nineteenth century, who determined the essential character of the Wallace Collection we see today." (www.wallacecollection.org [3])
