Sir Andrew Mitchell (1708–1771) was a British diplomat noted for his service as envoy to the court of Frederick the Great during the Seven Years' War.
His legal and intellectual interests took him frequently abroad, and in 1735 he formed a close friendship with Montesquieu in Paris.
He took up a broad spectrum of intellectual pursuits that encompassed ancient and modern history, art, literature, and moral philosophy;[1] in 1736 he was elected a Fellow of the Royal Society.
He was a commissary in Brussels for negotiating a commercial agreement with Austria and the Netherlands from 1752 to 1755 and an envoy to Prussia from 1756 to June 1765 and from December 1765 to his death.
Mitchell stayed with Frederick, recording his observations of the king at war in his journals, until his recall in 1764.
