The earliest known portrait,  attributed to Kneller, is a head and shoulders of c.1700owned by the Sloane-Stanley family at Paultons. A portrait by Kneller of 1716 engraved by Faber junior, 1729, was given by the sitter to the Royal Society and another by Thomas Murray of c.1725, engraved by Faber junior in 1728, was in the Royal College of Physicians by 1733 when noted there by Vertue 'Sir H. Sloane. at len'.  A whole length in scarlet and rose MD gown, painted in 1730 by Richardson, was presented by the sitter to Oxford in the following year.  A seated whole length in the British Museum showing the sitter as president of the Royal Society is ascribed to Vanderbank. A statue by Rysbrack is in the Chelsea Physic Garden  and the related terracotta bust, in the British Museum.
