William Wyndham (1759–1834), Lord Grenville

William Wyndham Grenville, first Baron Grenville, Prime Minister during the passage of the Abolition of the Slave Trade Act in 1807, appears in this 1810 portrait at the Hunterian Museum. Grenville's brief ministry achieved one of the great humanitarian reforms of British history, and this portrait records one of its principal architects. Phillips's documentation of the political class provides visual evidence of the men who shaped British policy.

Grenville is presented with the dignified bearing of a former prime minister. Phillips's competent handling captures the politician's measured intelligence without dramatic embellishment. The composition follows standard conventions of political portraiture, with dark costume and minimal background directing attention to the face.
