The Traveller spreads out before us the life and times of George Forster, who journeyed to the far reaches of the known world, and whose radical ideas about humanity, equality and freedom challenged the worldviews of eighteenth-century Europe.

Andrea Wulf paints a picture of a man of profound curiosity and brilliance. He joined Cook’s second voyage at the age of seventeen, an exploration of vast contrasts from the icy world of Antarctica to tropical islands of the South Pacific. Studying the diverse nature, peoples and cultures he encountered, he came back imbued with a deep belief in the equality of races – an understanding far ahead of his time. On his return he was feted in England, France, Germany and Poland, using his fame to advocate for freedom and women’s rights and against empire, racism and slavery. Wulf traces how Forster – inspired by the French Revolution – became a leader of the short-lived Republic of Mainz, before being declared an outlaw in Germany and forced into exile in Paris during the Reign of Terror.

Vivid, engaging and drawing on Forster’s rich correspondence almost entirely unpublished in English, The Traveller recounts an extraordinary, passionate life largely forgotten by history.
