Daniel Daulby was a Liverpool brewer and collector of prints and drawings who retired to Rydal Mount, Westmoreland in 1796. Celebrated in his own lifetime as perhaps the greatest British collector of Rembrandt etchings, he published a catalogue of them that year. Daulby was the brother-in-law of the historian, poet, art collector, lawyer, politician and philanthropist, William Roscoe. His posthumous sales took place at Thomas Vernon's, Liverpool on 12 August 1799 and eight following days; his prints were sold at Christie's on 14 May and three following days. His portrait by Richard Tate is in the Walker Art Gallery and various papers are at the Liverpool Record Office. See further: Farington Diary, vols 1, 2 & 3 passim and M. Hopkinson in exh. cat.
