This work is an important addition to the National Gallery’s British collection. The Gallery currently holds examples of formal and full-length works by Lawrence – John Julius Angerstein, aged about 55, about 1790; John Julius Angerstein, aged over 80, 1824; and Queen Charlotte, 1789 – but this painting exemplifies Lawrence’s influential but more informal depiction of children and families. 

Its inclusion in the collection will enable Gallery visitors to appreciate the breadth of Lawrence’s repertoire. The oval portrait depicts the 16-year-old sitter in motion, her head turned towards the viewer in a pose that has a long tradition in the history of portraiture. However, Lawrence brings a freshness to the work, reflected in the informality and economy of his brushwork.

The Hon. Emily Lamb went on to become an influential, politically prominent society hostess. She first married Peter Leopold Clavering-Cowper, 5th Earl Cowper. After his death, in 1839 she married Henry John Temple, 3rd Viscount Palmerston, who served twice as Prime Minister between 1855 and 1858 and again from 1859 to 1865. Her brother, Viscount Melbourne, also served as Prime Minister.
