Sir John Burdon Sanderson

Leslie Ward ('Spy') renders the physiologist Sir John Scott Burdon Sanderson in a loose, full-length caricature typical of *Vanity Fair*'s 'Men of the Day' series. The figure leans casually against a plain wooden chair, one hand pocketed, dressed in a dark frock coat, waistcoat, and grey trousers — the uniform of Victorian professional respectability. Ward exaggerates Sanderson's long, angular jaw and swept-back hair, giving him a slightly gaunt, distracted air that suits a man better known for laboratory precision than social dash. The composition is clean and uncluttered, the background a pale cross-hatched wash. The signature 'Spy' appears lower left. Sanderson, a pioneer in cardiac electrophysiology, was a natural subject for a magazine that celebrated institutional eminence.
