An inspiring biography of the remarkable naturalist, explorer and revolutionary, by the bestselling author of The Invention of Nature

George Forster was a man out of time: he journeyed to the far reaches of the known world and challenged the worldviews of eighteenth-century Europe with radical ideas about equality and freedom. Celebrated during his lifetime, he knew Goethe, Benjamin Franklin, Mary Wollstonecraft and Alexander von Humboldt but has since been largely forgotten by history.

The Traveller seeks to restore Forster as one of the great visionaries of his era. At the age of seventeen he joined Captain Cook’s second voyage – an exploration of vast contrasts from the icy world of Antarctica to the tropical islands of the South Pacific. A brilliant mind driven by boundless curiosity, he studied the diverse nature, people and cultures he encountered and came back imbued with a deep belief in the equality of races. On his return he was feted in England, France, Germany and Poland, using his fame to advocate freedom and human rights and argue against empire, racism and slavery. He admired strong and educated women and was proud to have daughters. The book traces how – inspired by the French Revolution – he became a leader of the short-lived Republic of Mainz and was eventually forced into exile in Paris during the Reign of Terror.

Following in Forster’s footsteps from Europe to Tahiti, and drawing on a wealth of correspondence mostly unpublished in English, Andrea Wulf paints a portrait of a remarkable, passionate figure unbound by place, people or establishment. She vividly conveys his extraordinary quest to find what connects us rather than what sets us apart.

'Andrea Wulf belongs to the small, splendid canon of writers unafraid to render fact with feeling' Maria Popova, creator of The Marginalian and author of Figuring
