This portraitback to top

There remains an element of doubt concerning the identity. NPG 1412 was first offered in March 1905 as a portrait of Humphry Davy (for whom see R. J. B. Walker, National Portrait Gallery, Regency Portraits) but two months later the owner was calling him Cavallo. [1] Costume suggests a date in the 1780s and the combination of scientific and artistic attributes [2] make the identification plausible. The likeness agrees with the Trotter engraving of 1787, but the Dance drawing and the Lind silhouette suggest heavier features.

Footnotesback to top

1) ‘I have gone into the question very carefully as to the portrait being that of Sir Humphrey Davy. As a scientific chemist, myself, I may say ...’ (28 March 1905), but by 27 May Mr Gabb was writing to say how important a figure Cavallo was in the evolution of electro-therapeutics (NPG archive).
2) For Cavallo as silhouettist, see S. McKechnie, British Silhouette Artists and their Work 1760-1860, 1978, pp 194-95, 382, and Apollo, XXII, 1935, pp 287-89.

1 It may be compared with Cuthbertson’s uninsulated twin-plate machine illus. W. D. Hackmann, John & Jonathan Cuthbertson, 1973, p 61, and first illus. in Cuthbertson, Algemeene-Eigenschappen van de electriciteit, 1782, II.

Provenanceback to top

1 In March 1935 Gabb said he had bought it at Christie’s in 1904 as Sir Humphrey Davy (note in NPG archive) - but such a purchase is now unidentifiable.
