R. L. Stevenson in his Edinburgh. Picturesque Notes, London, 1879, p. 4, has a footnote in which he says:
'A man in a frock-coat looks out of place upon an Alp or a Pyramid, although he has the virtues of a Peabody and the talents of a Bentham.'
Professor J. H. Burns (Emeritus Professor of History, UCL and a past director of the Bentham Project) forwarded the reference to us. He added in his note, that the juxtaposition with the philanthropic George Peabody (1795-1869, of the eponymous buildings) is interesting.
