⁂ Richard Heber (1773-1833), book collector and one of the 18 founder members of the Roxburghe Club, who amassed an enormous library of well over 100,000 volumes filling several houses in England and on the Continent. He frequently bought more than one copy of a book, stating "No gentleman can be without three copies of a book, one for show, one for use, and one for borrowers." After his death his library was dispersed in sixteen sales, thirteen in London, two in Paris and one in Ghent.
